To use MCQs effectively for revision, start by selecting a chapter and attempt its corresponding MCQs without prior preparation to gauge your understanding. Analyze the results to identify weak areas and focus your revision on those topics. Revisit the chapter, making notes on key concepts. After thorough revision, reattempt the MCQs to measure your improvement. Regular practice with chapter-wise MCQs consolidates your learning and helps you retain information longer, ensuring a more comprehensive grasp of the subject material before exams.
