Preparing for UPSC using PYQs doesn’t mean studying questions alone. It means using PYQs to decide what to study and how deeply to study it.

Start by solving PYQs topic-wise, then go back to the syllabus and basic sources to understand the concepts behind those questions. This approach helps you focus only on relevant areas instead of covering everything randomly.
Over time, PYQs begin to act like a guide for revision, concept-building, and answer-writing practice. You still need standard books and current affairs, but PYQs can become the backbone of your preparation strategy.
