Effective review strategies for the Mains exam include active recall, spaced repetition, and group discussions. Candidates should regularly revisit topics covered in their syllabus to reinforce memory retention. Employing active recall techniques, such as self-quizzing, can significantly enhance understanding. Spacing reviews over time rather than cramming allows for more profound learning. Engaging in group discussions fosters diverse perspectives and clarifies doubts. Additionally, practicing previous years’ papers helps familiarize candidates with the exam format and question types, ultimately strengthening their performance on the Mains examination.
