Most revision plans fail because they assume perfect discipline. This one assumes ordinary days.
Week 1 - Map the syllabus. List every chapter and mark it strong, average or weak. Do not study yet. Most students discover the weak list is shorter than the anxiety suggested.
Week 2 - Attack the weak list only. Give the hardest topics your best hours of the day. Solve problems rather than re-reading notes, because recognition is not the same as recall.
Week 3 - Full papers under timed conditions. One paper, one sitting, no phone. Then mark it honestly. The mistakes found here are worth more than another week of reading.
Week 4 - Revise mistakes, formulas and the average list. Do not learn anything new in the last five days; it displaces what is already secure.
Throughout: sleep properly. A tired brain does not retain. Students who sleep well and study six focused hours consistently outperform those who study twelve exhausted ones.
If a subject is not improving despite effort, that is the moment to bring in a Quick Tutor rather than the week before the exam.
