How long should you study for each exam?

The common ranges for 14 exams in one table, and how to work out where you fit.

The numbers

These are the ranges students and prep programs commonly plan around. They are starting points, not rules: your background, your target score and how recently you studied the material move you up or down the range.

Test lengths come from each exam’s official site and can change, so check before you book. Each exam name links to a free plan that turns your own date and hours into a week-by-week schedule.

Where you fit in the range

  • Use the low end if you studied the material recently, your practice scores are already near your target, or the exam is pass/fail and you’re comfortably passing practice tests.
  • Use the high end if it’s been years since the coursework, your first practice test is well below your target, or you’re aiming for a competitive score.
  • Take a practice test first. It tells you more than any table. Plan from the gap between that score and your target.

Turn hours into weeks

Divide your hours by what you can really study each week. 200 hours at 4 hours a day, 5 days a week, is 10 weeks. If that runs past your test date, either add hours per week or move the date. The exam countdown shows how many study hours you have left before a date.

Spread it out

The same hours spread over more weeks beat the same hours crammed into fewer. Spacing your review out over time is one of the most reliable findings in learning research. Leave the last few days light, and sleep properly before the exam.
