Aspirants can effectively revise their study materials before the exam by employing techniques like active recall and the Spaced Repetition System (SRS). Creating concise summary notes and flashcards enables quick review of key concepts. Engaging in self-assessment through mock tests and quizzes helps identify weak areas requiring additional focus. Incorporating group discussions can facilitate collective learning, while teaching others can reinforce understanding. A well-structured revision schedule that allocates adequate time for each topic ensures comprehensive coverage before the exam.
