Effective use of summary notes for revision before exams involves organizing information concisely for quick review. Candidates should distill core concepts, important dates, and key terms into manageable notes. Utilizing methods like bullet points, mind maps, or charts can make complex information more digestible. Summary notes should be regularly reviewed to reinforce memory retention and identify areas that need further study. Additionally, candidates should practice retrieval by summarizing concepts without looking at their notes, enhancing recall abilities crucial for the high-pressure exam environment.
