Work backward from the test date
Pick your test date first, then count back. Three to four months of regular work suits most people better than an intense final month, because the spacing research is clear that the same hours spread across weeks retain more than the same hours compressed. Reserve the last week for review and logistics rather than new material. Register early: the College Board publishes registration deadlines, late-registration windows, and any accommodation request deadlines, and the accommodation timeline in particular runs far longer than people expect. Check those dates on their site rather than assuming, because they move each cycle and a missed deadline is not a study problem you can revise your way out of.
Structure the weeks around full practice tests
Take a full, timed practice test early — before you feel ready — and use the section breakdown to decide where the hours go. That early attempt is a study session as well as a diagnostic, which is what the retrieval-practice research describes. Then alternate: targeted work on your weakest areas during the week, a full timed section or test at intervals to measure whether the work moved anything. The College Board publishes official practice material, and official practice is worth more than third-party practice for one specific reason: it is the only source whose question style is definitionally accurate. Log each attempt with what you predicted beforehand, because a persistent gap between prediction and score is worth knowing before test day rather than after.
Settle the logistics before the last week
Know your test centre and how long it takes to reach at that hour of the morning, and confirm what identification is required and what you may bring — the College Board publishes the current list, and it is the only list that governs. Have your admission ticket sorted days ahead, not the night before. Sleep matters more than a final revision session, and the last-week gains from cramming are small compared with what tiredness costs on a long timed test. The exam-day checklist in the free kit covers the practical items; the point of settling them early is that decision-making on the morning is the thing you least want to be doing.
