How many mock tests and previous years’ question papers should students practise, and how should they use these to identify gaps in their preparation?

Students should aim to practise 20–30 full-length mock tests in the final phase of NEET preparation, alongside previous years’ question papers. The focus should be on quality rather than quantity: analyse each test to identify weak topics, conceptual errors, time-management issues, and negative marking. Maintain an error log, revise the topics where mistakes occur, and track scores over time to measure improvement and guide further preparation.
