How do I analyse my mock test performance for improvement in UPSC Prelims exam?

To improve, categorize every mistake into three buckets: conceptual gaps (need more reading), silly errors (need better focus), or logical failure (flawed elimination).
Analyze the "50-50" guesses specifically—if most are wrong, your intuition needs recalibration.
Review solutions for all questions, not just incorrect ones, to learn faster alternative methods.
Finally, track your accuracy ratio (Correct vs. Attempted) to find your optimal "risk zone" for the actual exam.
