How do I analyse my weak areas after each UPSC mock test?

To effectively analyze weak areas, categorize every incorrect or unattempted question into three buckets: Conceptual Gap (didn't know it), Logical Error (guessed wrong), or Silly Mistake (misread the question).
Review the solutions immediately while your thought process is fresh.
For conceptual gaps, revisit the source material and update your notes. For logical errors, refine your elimination techniques.
Track these errors in a logbook to identify recurring patterns—like consistently missing "not correct" statements or failing in Geography—and adjust your study schedule to prioritize those high-risk zones.
