Study by unit weighting, not evenly.

With the official course and exam description for your subject. It lists the units, what share of the exam each one is worth, the skills assessed and the exam structure — and most students never open it. That document turns "revise everything" into a ranked list, which is the whole difference between a plan and a wish.

By exam weight and by how shaky you are, not evenly. With eight weeks at six hours a week, the calculator puts about 8.7 hours into each shaky unit and 2.8 into each strong one for review, after reserving time for timed practice. With three weeks and five weak units it drops to 1.6 hours each — which is the honest signal that some units will get a lighter pass, so pick them by weighting.

Test yourself from memory rather than rereading. Recalling an answer without looking builds it in; highlighting feels productive and mostly isn't. Space review across days, mix topics, and keep a log of every question you got wrong with the reason — rereading that log weekly is the highest-value habit in the plan.

Official released free-response questions and their published scoring guidelines, which are free and are the closest thing to the real exam. Mark your own answers against the guidelines — you'll see that points are awarded for specific things rather than general quality. Ask your teacher what official practice they can give you access to.

Sleep is part of the plan, not a reward for finishing — a tired brain scores lower. Build in one clear day off a week, keep exam week to light review rather than new material, and remember that scores of 3, 4 and 5 all represent real achievement. If the pressure feels constant or you're not sleeping, tell a teacher, school counsellor or parent early rather than pushing through alone.
