UPSC aspirants often underestimate the power of Previous Year Questions (PYQs) in shaping their preparation strategy. While PYQs are a treasure trove for understanding question trends, weightage, and difficulty levels, many candidates make critical mistakes that reduce their exam efficiency.

Common errors include skipping PYQs, focusing only on answers, ignoring analysis, and failing to link questions with current affairs. Avoiding these mistakes helps aspirants understand the UPSC pattern, prioritise high-yield topics, and strengthen exam readiness.
