Suggested UPSC Prelims preparation strategy using AajExam: start with the most recent UPSC Prelims previous year paper to establish a baseline. Identify your two weakest sections from the analytics, then spend 7-10 days revising those sections from notes and topic-wise quizzes. After that, alternate one PYQ shift per day with full-length practice tests until you have solved every available paper. The week before the actual UPSC Prelims exam, re-attempt 4-5 of your weakest tests — second attempts should consistently be 15-20% faster with measurably better accuracy.
