8. Post-Mock Test Analysis Protocol
Taking a mock test without reviewing performance yields limited improvement. Allocate at least 90 minutes after every 2-hour test to complete this post-analysis routine:
- Error Audit: Divide incorrect responses into three distinct categories: Factual Gap, Misread Question Stem, or Careless Calculation Error.
- Unattempted Question Review: Evaluate skipped questions to determine whether lack of subject knowledge or time pressure prevented an attempt.
- Error Notebook Logging: Record missed Bihar GK facts, scientific terms, and scheme details into a dedicated notebook. Review these notes before taking your next mock test.
- Cutoff Benchmarking: Measure your net score against recent official BPSC category cutoffs to monitor progress.
