SSC CGL 2027 Examination Blueprint: Comprehensive Tier-1 & Tier-2 Preparation Guide
For graduates in India, securing a Group 'B' or Group 'C' post by passing the Staff Selection Commission's Combined Graduate Level Examination is one of the most desirable achievements. This exam serves as a route to a variety of important administrative positions, including Assistant Section Officer (ASO) in the Central Secretariat Service (CSS), ASO in the Ministry of External Affairs (MEA), Inspector of Income Tax, Central Excise / GST Inspector, Preventive Officer, Examiner, and Sub-Inspector in the Central Bureau of Investigation (CBI).
The process of the examination consists of two computer-administered stages. The first stage, Tier-1, includes 100 multiple-choice questions worth a total of 200 marks and must be completed within a 60-minute period, with a negative marking penalty of 0.50 marks (that is, one-fourth of a mark for each incorrect answer). It is important to note that Tier-1 serves only a qualifying purpose; while your performance in this stage allows you to pass the first phase, it in no way affects your final merit position. The decision regarding your final appointment is entirely based on Tier-2 Paper-I. This is a 390-mark combined examination made up of six sections, each lasting 60 minutes, and carries a significant penalty of -1.00 mark (one-third mark deducted for each wrong answer). Nevertheless, even if you obtain the highest score in Tier-2, your selection could still fail because of two compulsory screening requirements: the 60-mark Computer Knowledge Test and the 15-minute Data Entry Speed Test (DEST).
The SSC CGL Mock Test 2027 testing platform provides individual, fully synchronized practice sections for both stages. It allows you to establish your Tier-1 qualifying level, check your endurance when using the fixed Tier-2 sectional timers, verify if your computer score reaches the higher cut-off needed for ASO and Inspector positions, and measure your actual typing error rate with the browser-based DEST simulator.
| Examination Metric | Tier-1 (Qualifying Gateway) | Tier-2 Paper-I (Final Merit Decider) | Practical Value for Candidates |
|---|---|---|---|
| Exam Mode | Online Computer-Based Test (CBE) | Online CBE plus DEST Typing Simulator | Full electronic testing environment matching TCS consoles |
| Total Questions | 100 questions (25 per subject) | 130 merit questions plus 20 computer questions | Tier-2 tests stamina over a period of two hours and thirty minutes |
| Maximum Marks | 200 marks (2.0 marks for each question) | 390 marks (3.0 marks for each question) | Your Tier-2 score out of 390 determines your All-India Rank |
| Exam Duration | 60 minutes (composite time) | 2 hours 15 minutes (Session I) plus 15 minutes (DEST) | Candidates must make sharp allocations of time within the locked 60-minute windows |
| Negative Penalty | –0.50 marks (one-fourth deduction) | –1.00 mark (a deduction of one-third for each wrong answer) | The penalty in Tier-2 is much more severe; blind guessing is penalized |
| Selection Status | Strictly qualifying (zero merit value) | 100% final merit decider | Passing Tier-1 gets you shortlisted; passing Tier-2 secures the post |
| Sectional Timers | None (free navigation between subjects) | Strict 60-minute locked windows | Any unused time in the Math section cannot be carried over to the English section |
| Mandatory Gates | Aggregate normalized qualifying cutoff | Computer Module (60 marks) + DEST (2000 keystrokes) | Failure in either of these gates results in immediate disqualification |
The Two Silent Disqualifiers: Computer Module and DEST Typing Test
Every year, over 10,000 candidates achieve a score higher than 320 out of 390 in Tier-2 but still fail to get any job offers.
This is due to the fact that competitors and coaching centres see the computer module and the typing test as just formalities; in fact, they do act as strict elimination filters.
Computer Knowledge Test (60 Marks): General Cutoff as compared to the Higher CPT Post Cutoff
The Computer Knowledge Test consists of 20 multiple-choice questions, each carrying 3 marks, which gives a total of 60 marks, and has to be completed within a strict 15-minute time limit right after Section II.
The commission officially states that the following marks are required to qualify:
- Candidates for the rank of General (UR) must obtain 30 per cent (that is, 18 marks out of 60).
- Candidates in the OBC/EWS category have to obtain 25 per cent (15 marks out of a total of 60).
- Candidates in the SC, ST, and PwD categories must obtain 20 per cent (12 marks out of 60).
The trick which surprises thousands of candidates is that for the most attractive posts in the examination the commission applies Higher Qualifying Standards (CPT cut-offs).
If you want a post such as Assistant Section Officer in the CSS, Assistant Section Officer in the MEA, GST Inspector, Preventive Officer, Examiner, or Postal Assistant, then scoring 18 marks is not enough. In the most recent recruitment cycles the higher qualifying standard for these posts has been between 27 and 36 or more marks out of a total of 60.
You will be automatically rejected from any post which is mandatory for the CPT even if your score in the written examination is 335 out of 390 and you get only 20 marks in the computer test. You will then only be considered for posts that are not part of the CPT, or end up with no post at all if all the non-CPT vacancies have already been filled.
On each practice mock test there is a dual-indicator scorecard which shows both your basic qualifying status and whether or not your score meets the higher CPT post benchmark.
Data Entry Speed Test (DEST): Typing 2,000 Key Depressions in 15 Minutes (5% Error Rule)
Following the short administrative break that occurred after Session I, the candidates must take Session II, which is the Data Entry Speed Test (DEST).
The rules for the DEST are strict:
- You need to type an English passage containing about 2,000 key presses in 15 minutes.
- That is equivalent to a typing speed of approximately 27 words per minute (WPM).
- The test is required for all positions, not only for clerical ones.
Even though 27 words per minute might sound fairly low in theory, it is difficult in practice. You are typing on a stranger's desktop keyboard in a noisy exam room, with a timer shown on the screen decreasing and the mechanical keys making noise nearby.
For General (Unreserved) candidates the maximum permitted error rate is 5 per cent (7 per cent for OBC/EWS and 10 per cent for SC/ST); should your error rate reach 5.1 per cent you will be disqualified from the whole selection process, regardless of whether your written score was 360 out of 390, since a single unforced typing error cancels out all the work you have already done.
The test website offers a live, browser-based DEST simulator which replicates the actual TCS interface. It stops keyboard shortcuts from being used, keeps a count of the keys you press, and displays to you in real time your error percentage in accordance with the official evaluation rules.
The SSC CGL Selection Architecture: Tier-1 Qualifying vs Tier-2 Merit
If you want to plan your daily study sessions properly then you must understand the structural differences between Tier-1 and Tier-2.
It is an error for a large number of candidates to spend 80% of their time on Tier-1, considering that Tier-2 can be dealt with afterwards. The fact that Tier-1 marks do not count towards your final rank shows that it is one of the most common tactical mistakes to concentrate too much on Tier-1 and at the same time neglect the more difficult parts of Tier-2 during SSC preparation.
Tier-1 Exam Reality: Why 150+ Marks Are Required Just to Qualify
Tier-1 is an elimination process by which the number of applicants is reduced from about 1.5 to 2 million to between 80,000 and 120,000 for Tier-2.
Because the paper consists of 100 questions to be solved in 60 minutes with no sectional time limits, the scoring pace is fast:
- In more recent exam cycles the normalized cutoff mark for Unreserved (General) candidates has been in the range from 140 to 153 out of 200.
- You need to aim for a net raw score of 150 or above in your practice tests to allow for differences in the difficulty level.
- In order to achieve a score of 150 or higher, one must answer between 75 and 80 questions with a degree of accuracy of at least 90%.
It is necessary to remember that a score of 180 in Tier-1 gives no mathematical advantage over a candidate who has scored 152; both candidates enter Tier-2 on a completely equal basis and start from zero.
Tier-2 Paper-I Breakdown: The 390-Mark Merit Decider
The last assignment and the specific group to which you will be assigned are entirely based on the score you get out of 390 in Paper-I of Tier-2.
Tier-2 Paper-I is conducted in a single continuous morning session lasting 2 hours and 15 minutes, divided into three strictly timed sections:
• Module 1: Mathematical Abilities (30 Questions | 90 Marks)
• Module 2: Reasoning & General Intelligence (30 Questions | 90 Marks)
Total Section I: 60 Questions | 180 Marks | 60 Minutes (Unused time cannot be transferred)
• Module 1: English Language & Comprehension (45 Questions | 135 Marks)
• Module 2: General Awareness (25 Questions | 75 Marks)
Total Section II: 70 Questions | 210 Marks | 60 Minutes
• Module 1: Computer Knowledge Test (20 Questions | 60 Marks | Qualifying Gate)
The negative mark being reversed: -0.50 for Tier-1 rather than -1.00 for Tier-2 punishing
A critical rule shift that catches students unprepared is the change in penalty severity between stages:
In the Tier-1 section, each question awards you a score increase of +2, whereas an incorrect answer leads to a deduction of 0.50 marks. The penalty is therefore one quarter (that is, a 25 per cent deduction).
In the Tier-2 section, each question carries three marks but deducts one mark for an incorrect answer. The penalty is one-third (a deduction of 33.33%).
The effect of making three wrong guesses in Tier-2 is that you lose three full marks – that is to say, one question which was answered correctly and is worth three marks is completely nullified.
In the case of Tier-1, four wrong answers are needed to nullify one correct answer, whereas in Tier-2 it is enough to have three incorrect answers to cancel one correct answer. Candidates who continue from Tier-1 to Tier-2 the practice of guessing loosely usually suffer a drop in their scores of between 20 and 30 marks because of the negative marking.
Subject-Wise Weightage Breakdown for Tier-1 & Tier-2
In order to operate efficiently you must understand how the area of focus for each subject changes from the qualifying screening stage to the final merit examination.
Mathematical Abilities & Quantitative Aptitude (Arithmetic & Advanced Geometry)
The Advanced Split (25 questions / 50 marks) includes a well-balanced combination of arithmetic topics (for example, percentages, ratios, profit and loss, time and work, and speed and distance) and advanced mathematics (such as algebraic identities, triangle geometry, circle tangents, 2D and 3D mensuration, and trigonometry).
The questions at tier 2 (30 questions / 90 marks) require a move towards solving problems that involve more than one step, the questions combining different topics for example circle geometry with coordinate geometry or volume calculations with percentage changes.
The paper now has between 2 and 3 required questions on Elementary Statistics and Probability (in particular those relating to the calculation of the mean, median, mode, standard deviation, and variance). Those topics were not included in the earlier exam papers prior to 2022.
Reasoning & General Intelligence (Deductive Logic & Tier-2 Critical Reasoning)
The section on Reasoning at the first level (consisting of 25 questions worth 50 marks) covers topics such as the recognition of patterns, including alphanumeric sequences, coding and decoding, analogies, classification, mirror images, paper folding, and Venn diagrams, and most candidates can finish it in 15 minutes.
The section on reasoning and intelligence at tier-2 level (30 questions / 90 marks) has the simple visual questions replaced by critical and analytical reasoning questions (numbering between 8 and 10). You are required to:
- A statement together with the assumptions (that is, the premises which are not stated).
- Statements together with the arguments, selecting only the strong ones from the weak ones.
- Cause and Effect relationships.
- Issues relating to what course of action to take (i.e. the evaluation of administrative decisions).
- Multi-condition data sufficiency questions.
English Language & Comprehension (Reading Comprehension, Vocab & Grammar)
The part of the test designated as Tier-1 on English (consisting of 25 questions and worth 50 marks) looks at candidates' memory of vocabulary (this including synonyms, antonyms, one-word substitutions, and idioms) and basic grammar (this involving error spotting, sentence improvement, the use of the active and passive voice, and direct and indirect narration).
The Tier-2 English Language paper has 45 questions and is worth 135 marks; it thus accounts for 34.6% of the total merit score of 390 and is by far the most important subject in the exam. It includes:
- The exam consists of three or four full Reading Comprehension passages, one of which is based on a narrative story and the other two being editorial passages concerned with economics, science, or social policy.
- A cloze test with between five and ten questions to check knowledge of vocabulary and contextual prepositions.
- The paragraph rearrangement known as Para Jumbles tests the logical structure of a paragraph.
General Awareness: Conquering Modern TCS Art, Culture & Multi-Statement Polity
The way questions are posed nowadays is different since earlier exam papers had simple questions consisting of a single line, for instance "Who built the Taj Mahal?", while the exam papers currently administered by TCS do not have questions which are based on simple recall.
The part dealing with Art and Culture (comprising six to eight questions) contains questions regarding the musical Gharanas (for example, Gwalior, Kirana, and Agra), the dancers who are involved in both classical and folk dance and the awards that they have received, traditional musical instruments, and the regional harvest festivals.
When dealing with a question on Indian Polity which involves several statements (usually between four and five): evaluate the constitutional articles by using formats that contain two or three statements (for example, "Which of the following statements regarding the writ jurisdiction of the High Court under Article 226 is correct?").
The part of the exam dealing with general science (which includes between 5 and 6 questions) includes the topics found in the NCERT textbooks for Classes 9 and 10, for example the IUPAC names of chemicals, the symptoms resulting from a deficiency of vitamins, the functions of different human organs, and the properties of the elements in the periodic table.

135-Minute Tier-2 Endurance Strategy: Managing Locked 60-Minute Windows
It being the case that the Tier-2 system allocates a fixed 60-minute time frame to each section means that minutes cannot be borrowed from one topic to help another.
When the 60-minute countdown in Section I is finished, the screen will automatically send in your answers before showing Section II. The table below outlines our recommended pacing strategy:
| Exam Section | Time Allotted | Target Questions | Recommended Division of Time | Target Net Marks |
|---|---|---|---|---|
| Section I: Mathematics and Reasoning | from minute 00 to 28 (28 minutes) | 26 to 28 questions | tackle the reasoning questions first (those on series, syllogisms and coding) and deal with the critical reasoning questions with care | 78 to 82 marks |
| From 28 to 56 minutes (28 minutes) | Questions 24 to 26 | solve the arithmetic and algebra problems as well as the multi-step geometry and statistics questions | 72 to 78 marks | |
| Between 56 and 60 (4 minutes) | Review Pass | Select 2 or 3 of the questions that were flagged and eliminate the answer options. | 6 to 9 marks | |
| Section I Total | 60 minutes (locked) | 52 to 56 attempts | be certain that your calculations on the scratch paper are clear in order to avoid sign errors | 156 to 168 marks |
| Section II: English and GA | From time 00 to 12 (12 minutes) | 20 to 22 questions | For the General Awareness questions, answer them directly. Read the question once and then either provide the answer or leave it blank within 20 seconds. | 45 to 55 marks |
| From minute 12 through to minute 54 (a duration of 42 minutes) | candidates should answer 40 to 42 questions | by solving problems in English grammar, vocabulary, the cloze test and by reading passages and this should result in between 115 and 125 marks. | 115 to 125 marks | |
| Between 54 and 60 (that is, 6 minutes) | Review Pass | go over the questions which contain difficult vocabulary and avoid making random guesses as there is a -1 penalty. | 6 to 9 marks | |
| Section II Total | lasts for 60 minutes (locked) | allows between 62 and 66 attempts | English carries 135 marks and the reading comprehension passages must be read carefully. | The marks achieved are between 166 and 185. |
| Section III: Computer Module | 15 minutes (locked) | 16 to 18 questions | particular attention should be given to MS Office shortcuts, networking, and memory units – a target score of 36 or more marks is to be aimed for | 36 to 45 marks |
| Combined Target | The total time allocated for the combined target is 2 hours 15 minutes | the number of attempts lies between 114 and 122 | in order to remain in the top merit selection group you should aim to obtain 325 or more out of 390 | 322 to 345 marks |

| Level 7 (4600 GP) – Position of Sub-Inspector with the Central Bureau of Investigation | Level 7 (4600 GP) | 321.00 Marks | 314.50 Marks | 325 or above Marks (standard cutoff) |
| Level 5 (2800 GP) – Auditor / Accountant (CAG / CGA) | Level 5 (2800 GP) | 308.00 Marks | 301.50 Marks | 315+ Marks (standard cutoff) |
| Level 4 (2400 GP) | Level 4 (2400 GP) | 301.00 Marks | 294.00 Marks | 308 or more Marks (with a higher CPT cutoff) |
Comment on scoring: Past cutoff scores can be used as a reference point rather than as certain predictions. The scores vary depending on the number of posts that are being advertised and on the difficulty of the exam. To secure the post you most want, you should achieve a score of 330 or higher out of 390 in your Tier-2 practice tests and at the same time make sure that your computer-based score is well above 35 marks.
Product Features: How Our Analytics Work
Our practice platform includes diagnostic tools built specifically for central staff selection examinations:
- For each stage there are individual diagnostic dashboards for Tier-1 (100 questions) and Tier-2 (150 questions) which monitor accuracy in all four subjects.
- In the case of Tier-2 mocks, the real TCS console is obtained by locking Section I after 60 minutes and then proceeding directly to Section II.
- The criterion indicating eligibility for both CPT posts is that on each Computer Module result you will find both the basic qualifying mark (18/60) and an indication of whether or not your score meets the higher qualifying requirement (30+/60) needed for ASO and Inspector posts.
- A DEST Typing Simulator that takes only 15 minutes: you will be able to check your typing speed straight within the browser, as the system keeps a record of each key press, disables shortcuts, and calculates your error rate according to the official evaluation rules.
- You are able to compare your raw score with your predicted normalized score against those of thousands of other candidates on our live leaderboard by using the Real-Time All-India Ranking and Percentiles feature.
- Adaptive Testing Engine: The questions you are given will become more complicated and involve more variables in geometry as your skills improve, and the system will also include more advanced statistics and more difficult critical reasoning passages.
- Detailed explanations are given for each question: for maths questions the digital sums and unit-digit shortcuts are emphasized, for reasoning questions logic trees are included, and for General Awareness questions the appropriate NCERT chapters are referenced.
🤖 AI-Based Weak Area Recommendation
Personalized AnalyticsIf you take practice exams without checking the mistakes you have made, you will make the same errors on the day of the actual exam. The automated AI diagnostic tool on our testing platform functions like a personal tutor by looking at your performance.
Here is how the analysis works:
- Take a full-length practice test and submit your answers.
- The engine keeps a record of whether each question is answered correctly, incorrectly, or is left unanswered for each module.
- If you get high scores in English and Arithmetic the dashboard will show those topics in red provided that you still lose marks on either the Tier-2 Critical Reasoning (Statement-Assumption) or the Computer Module (Networking Protocols).
- The system provides an automatic recommendation about your study by saying: "As your accuracy dropped below 45% in the Tier-2 Critical Reasoning section (Statement-Assumption Logic) and in the Computer Module (Internet OSI Layers & Protocols), you should go through our reference notes concerning the rules for testing assumptions and those relating to TCP/IP port functions and then carry out our 20-question targeted drill before attempting your next full mock test."

Section-wise Weightage, Preparation Strategy & Recommended Books
Follow these subject guidelines to build balanced speed and accuracy across both tiers:
1. The subject of mathematics and quantitative aptitude (50 marks in Tier-1 / 90 marks in Tier-2)
To study, you need to learn your multiplication tables going up to 30, remember the squares up to 50, know the cubes up to 30, and be able to convert fractions into percentages. For more advanced mathematics, draw up your own formula sheet which includes the circle tangent theorems, triangle similarity, and trigonometric identities. You should also practice working out the mean, median, mode, and standard deviation for Tier-2 statistics.
The books that are recommended are Quantitative Aptitude for Competitive Examinations by R.S. Aggarwal, Advance Maths by Rakesh Yadav, and Play with Advanced Maths by Abhinay Sharma.
2. Reasoning and General Intelligence (Marks: 50 for Tier 1, 90 for Tier 2)
As for Tier-1, you should work on visual pattern recognition and coding-decoding each day, and with regard to Tier-2, you must focus on Critical Reasoning by learning how to identify unstated assumptions, evaluate the strength of the arguments, and assess cause-and-effect statements without allowing your personal biases to influence your answers.
The books that are recommended are 'A Modern Approach to Verbal and Non-Verbal Reasoning' by R.S. Aggarwal and 'Analytical Reasoning' by M.K. Pandey.
3. English Language and Comprehension (Weight: 50 Marks Tier 1, 135 Marks Tier 2)
To improve your reading speed and acquire business vocabulary, you should read reputable editorial newspapers every day. You also need to review the fundamental grammar rules, including subject-verb agreement, the use of modifiers, parallelism, and conditional clauses. Each day you have to do two cloze test paragraphs and three reading comprehension passages as practice.
The books that are recommended are Word Power Made Easy by Norman Lewis; Objective General English by S.P. Bakshi; and English for General Competitions by Neetu Singh (from Plinth to Paramount).
4. General Awareness (Weight: 50 Marks Tier 1, 75 Marks Tier 2)
When studying, you should focus on the NCERT Science textbooks for classes 9 and 10. You need to revise the general knowledge topics which are likely to come up often, for example the Gharanas of classical dance, musical instruments, festival calendars, and the UNESCO sites. Study the Indian Constitution in detail, paying special attention to Articles 12 to 51A, the provisions concerning emergencies, and the parliamentary committees.
The books that are recommended are Lucent's General Knowledge, the NCERT Science Textbooks for Classes 9 and 10, and the Pinnacle SSC General Studies chapter-wise solved papers.
5. Computer Knowledge Module (60 Marks – Tier 2, Section III – the Qualifying Gate)
When studying, you should concentrate on computer hardware components, the input-and-output ports, and the memory hierarchy (which encompasses cache, RAM, and ROM). You need to learn the most commonly used keyboard shortcuts in MS Office, particularly those relating to formulas in Word and Excel. Make sure to review the basic principles of networking such as the OSI model layers, TCP/IP, DNS, and the various kinds of cyber threats, for example trojans and ransomware.
The books that are recommended are 'Objective Computer Awareness' by Arihant Publications and 'Lucent's Computer'.
15 Common Mistakes Aspirants Make in SSC CGL Prep
Avoid these frequent preparation errors to protect your score and your eligibility:
- Treating Tier-2 Negative Marking in the Same Way as Tier-1 means that when you make careless guesses and there is a strict -1.00 mark penalty, you lose three marks for every three wrong answers.
- If you set your aim at merely meeting the lowest mark required for qualification in computers, you will eliminate yourself from being considered for posts that are required for the CPT, such as ASO and GST Inspector.
- Delaying typing practice until after the Tier-2 results have been announced: not carrying out keyboard typing until the written exams have been marked and failing to meet the 5% error limit on the day of the exam.
- Focusing too much on Tier-1 at the expense of Tier-2: spending months attempting to raise Tier-1 scores above the qualifying level while not tackling the Tier-2 problem solving.
- In the Tier-2 level, people ignore Critical Reasoning by focusing only on traditional visual puzzles and omitting the Statement-Assumption and Cause-Effect questions.
- Conducting Tier-2 training by means of portals that allow free movement between sections, without establishing a time discipline of 60 minutes.
- Not addressing the topics of Statistics and Probability—such as standard deviation, variance, and probability—means losing between 6 and 9 marks that could have been obtained in the Tier-2 Math paper.
- Attempting to recall math shortcuts without understanding the underlying concepts leads to making errors when the questions are changed.
- The fact that people study general knowledge from outdated one-liner books changes the situation since these books include general knowledge lists which do not match the more detailed questions now asked in the examinations.
- When peopleskim editorial passages in Tier-2 English they read too quickly and thus fail to answer the nuanced inference questions.
- Carrying out Scratch Math Work in a disorganized manner: writing the calculations messily on rough paper, which results in sign errors and numbers being misread during the timed sections.
- Not keeping track of the time in Section I and spending 35 minutes on the Math section, which left too little time for the Reasoning section.
- Spendting study hours on memorising letter formats for the discontinued Tier-III section since the descriptive essays had been permanently taken away from the examination.
- Relying too much on papers based on unverified memory: practicing with unofficial question sets that have incorrect numbers and defective answer keys.
- Taking tests without using an error notebook—that is, taking practice papers without writing down and then reviewing the questions that were missed in a special notebook.
Here’s why you should try the SSC CGL Mock Test 2027:
The best way to get ready for the pressure you'll experience on the day of the exam is to take some realistic practice tests.
- You can get a good idea of what the actual testing environment is like by becoming used to the fixed 60-minute sectional transitions, the colours of the question palette, and the automatic submission system.
- You will learn to exercise discipline when choosing questions by deciding which ones to solve at once and which difficult geometry problems to leave behind on your first pass.
- You can assess your readiness concerning both the computer and your typing by using our dual CPT indicator together with the live DEST typing simulator to ensure that you meet all the qualification requirements.
- You will be able to accurately identify your weak points by means of diagnostic heatmaps, which show the chapters in which you lose marks, so that you can most effectively focus your study time on those areas.

Final Practical Advice: Accuracy and Discipline in Tier-2
In the Tier-2 level the actual difficulty consists in coping with the negative marking of -1.00 for each incorrect answer.
Since each wrong answer erases one-third of the marks of a correct answer, uncontrolled guessing can quickly bring your score below the merit level:
- If you can't eliminate any of the answer choices, then leave the question blank. You will get no marks for leaving a question unanswered, and if you make an incorrect guess you will lose one mark and have your total score reduced.
- When attempting questions, you should only do so for those that you are certain about after having completely confidently eliminated at least two options.
- To maintain good typing discipline, type for fifteen minutes each day using a standard physical keyboard; just as important as achieving a good score on your written paper is keeping your error rate under 5%.
It is important to keep a special revision notebook. Whenever you have taken a practice test, you should write down all the questions that you answered incorrectly, determine the exact calculation or conceptual error responsible for each mistake, and then go through your notes before beginning the next test. It is only through regular review and by maintaining a disciplined pace that you can secure a place on the final merit list.
