When to Start Studying for AP Exams — 2027 Month-by-Month Study Plan
The most common AP regret isn't "I didn't study enough" — it's "I started too late." With 2027 AP exams beginning May 3, 2027, you have about six months. That's plenty of time if you use it in the right order, and not nearly enough if you wait until April.
Quick answer: Start light, focused review in January for most exams — or November if you're taking three or more APs or self-studying. Begin full timed practice tests in March, and spend the final two weeks on weak spots, not new material.
When Should You Start Studying?
Keeping up in class is your main preparation for most of the year. Dedicated exam prep — reviewing earlier units, drilling the exam format, timed practice — should start earlier than most students think:
| Your situation | Start exam-specific prep | Weekly time per exam |
|---|---|---|
| 1–2 APs, keeping up in class | Early February | 1–2 hours, rising to 3–4 in April |
| 3–4 APs | January | 1–2 hours, rising to 3–4 in April |
| 5+ APs, or exams in the same week | November–December | 1 hour now, more from March |
| Self-studying (no class) | Now — ideally September | 4–6 hours throughout |
| Aiming for a 5 on a hard exam | December–January | 2–3 hours, rising to 4–5 in April |
The reason to start early isn't to cram more — it's spacing. Reviewing Unit 1 for 30 minutes in January, again in March, and again in April beats three hours on it in late April.
How Much Time You Actually Have
Counting from November 1, 2026 to the first exams on May 3, 2027, you have about 26 weeks. Take out winter break and spring break and most students have roughly 22 usable weeks. Check your own exam dates in the 2027 AP exam schedule — Psychology and Comparative Government aren't until May 14, while Biology and Human Geography are on day one.
Month-by-Month AP Study Plan (Nov 2026 – May 2027)
November: Lock in the basics
- Register. College Board's ordering deadline is November 13, 2026, and your school's is earlier. See the registration deadline guide.
- Learn the exam format for each subject — number of MCQs, FRQ types, timing. Our exam length guide lists every exam.
- Start a running "mistakes list" for each class: every quiz or test question you miss goes on it. This becomes your best review material in April.
December: Review what you've already covered
- Before winter break, briefly review fall units — they're what you'll have forgotten by May.
- Over break, take one diagnostic — a half-length practice set per subject — just to see where you stand. Don't stress the score.
- Make or download a one-page summary for each unit finished so far. Our AP cheat sheets cover the major exams.
January: Build a weekly routine
- Set a fixed weekly block per exam (for example, Tuesday and Saturday mornings) — consistency matters more than length.
- Alternate: one session reviewing an old unit, one session practicing the exam format (a set of MCQs or one FRQ).
- Read official scoring guidelines for past FRQs. Knowing what graders reward is the fastest point gain on most exams.
February: Attack your weakest units
- Use your mistakes list and diagnostic to rank units from weakest to strongest. Spend most of your time on the bottom three.
- Do FRQs under time limits. Many students know the content but run out of time on the free-response section.
March: Start full practice tests
- Take your first full, timed practice exam per subject. Try our free AP practice tests.
- Score it with the matching AP score calculator to see whether you're on track for a 3, 4, or 5 — and which section is costing you points.
- March 12, 2027 is also the last day schools can order exams (with a late fee), if you still need to add one.
April: Peak review
- Increase to 3–5 hours per exam per week.
- Take a second full practice test in mid-April and compare it to March.
- Shift from learning new material to practicing retrieval: flashcards, blank-page recall, and timed FRQs.
May: The final two weeks
- Study for exams in the order you take them. Your first exam gets your full attention until it's done.
- Review your mistakes list and summary sheets — not new textbooks.
- Do one last timed FRQ set two or three days out, then taper. Sleep matters more than a final cram the night before.
If You're Taking Several APs
With three or more exams, sequencing decides everything:
- Find your crunch week. In 2027, Week 1 (May 3–7) holds Biology, Chemistry, U.S. Government, World History, and APUSH. If most of your exams fall there, your prep needs to peak a week earlier.
- Start the hardest exam first. Pass rates vary a lot — see our AP difficulty ranking. Give the toughest one the longest runway.
- Don't let an easy exam slide. Students often under-prepare for exams like Psychology or Human Geography because the class feels easy — but both have pass rates in the mid-50s.
- Check for conflicts. If two of your exams share a session, one moves to late testing (May 17–21) — and you get an extra week for it.
A Sample Weekly Schedule (3 APs, February)
| Day | Focus | Time |
|---|---|---|
| Monday | AP Bio — review one older unit | 40 min |
| Tuesday | APUSH — one timed SAQ or LEQ | 45 min |
| Wednesday | AP Calc — 15 MCQs from past units | 40 min |
| Thursday | Rest or catch-up | — |
| Saturday | One timed FRQ per subject + check against scoring guidelines | 2 hours |
| Sunday | Update mistakes lists, flashcard review | 45 min |
That's about 5–6 hours a week across three exams — manageable alongside normal homework, and it compounds. By April, you're reviewing material for the fourth or fifth time instead of the first.
Common Study Mistakes to Avoid
- Re-reading notes instead of testing yourself. Recall and practice questions build memory; re-reading builds false confidence.
- Skipping FRQs. Free response is often worth 40–60% of the score and is where structured practice pays off most. Start with our FRQ guides.
- Never taking a full timed test. Stamina and pacing are skills. You should not be sitting a full-length AP exam for the first time in May.
- Aiming for 100%. The curve is generous on many exams — often around 60–70% of total points earns a 5. See the AP score curves to know your real target.

When should I start studying for AP exams?
For most students, January is the right time to start exam-specific review, with full timed practice tests starting in March. If you're taking three or more APs or self-studying, start in November or earlier.
How many hours a week should I study for an AP exam?
About 1–2 hours per exam per week from January through March, rising to 3–5 hours per exam per week in April. Self-studying students should plan 4–6 hours per week throughout.
Is one month enough to study for an AP exam?
It can be enough to pass if you've kept up in class all year, but it's rarely enough for a 5 on a harder exam. A month of focused practice tests and FRQs is far better than a month of re-reading notes.
When do 2027 AP exams start?
The 2027 AP exams run May 3–7 and May 10–14, 2027, with late testing May 17–21.
How many practice tests should I take before the AP exam?
Aim for at least two full, timed practice tests per subject — one in March and one in mid-April — plus timed FRQ practice in between.
