Introduction: Why the Last 48 Hours Matter
The two days before the AP Statistics exam can make or break your score. At this point, you’re not learning brand new material — you’re:
- Reviewing key formulas and conditions.
- Practicing exam-style problems.
- Building confidence and stamina.
This guide gives you a 48-hour AP Statistics review plan, complete with RevisionDojo’s tools for flashcards, FRQ practice, and formula mastery.
Step 1: Know What to Focus On
You don’t have time to cover everything. In the last 48 hours, focus on:
- Formulas + conditions (z-tests, t-tests, chi-square, regression).
- Sampling distributions (means vs proportions).
- Confidence intervals + hypothesis tests.
- Calculator shortcuts (TI-84, Desmos).
- Common AP exam mistakes.
RevisionDojo’s formula sheets and mistake logs are perfect for this stage.
Step 2: 48-Hour AP Statistics Study Plan
Here’s how to divide your final review:
Day 1 Morning (3–4 hours)
- Review Units 1–4 (exploring data + probability).
- Focus on graphs, distributions, and two-variable data.
- Do 15–20 MCQs from RevisionDojo practice sets.
Day 1 Afternoon (3–4 hours)
- Review sampling distributions + central limit theorem.
- Work two FRQs from past exams.
- Watch calculator tutorials for regression + inference.
Day 1 Evening (2–3 hours)
- Make a formula sheet by hand.
- Review common mistakes list.
- Light review: flashcards + playlists for focus.
Day 2 Morning (3–4 hours)
- Review confidence intervals + hypothesis testing.
- Practice one full FRQ on inference.
- Work through 10 multiple-choice problems under timed conditions.
Day 2 Afternoon (2–3 hours)
- Review chi-square + regression inference.
- Focus on conditions (random, normal, independent).
- Do a mini timed practice (20 MCQs, 1 FRQ).
Day 2 Evening (2 hours max)
- Quick flashcard review of formulas.
- Read RevisionDojo’s exam-day checklist.
- Relax and sleep — no cramming past midnight.
Step 3: Use Active Review, Not Passive
Avoid just rereading notes. Instead:
- Solve practice problems.
- Write conclusions in full sentences (with context!).
- Teach yourself concepts out loud.
- Use RevisionDojo’s flashcards to test recall.
Step 4: Focus on Formulas + Conditions
Here are the must-know formulas and conditions to write on your sheet:
- 1-prop z-test: z=p^−p0p0(1−p0)nz = \frac{\hat{p} - p_0}{\sqrt{\frac{p_0(1-p_0)}{n}}}
- 2-prop z-test: Difference between proportions.
- 1-sample t-test: xˉ−μ0s/n\frac{\bar{x} - \mu_0}{s/\sqrt{n}}
- Chi-square test: χ2=∑(O−E)2E\chi^2 = \sum \frac{(O-E)^2}{E}
- Regression t-test: slope ÷ SE(slope).
Conditions Checklist:
- Random sample/assignment.
- Normal distribution (np ≥ 10, n ≥ 30, CLT).
- Independence (10% condition if sampling).
RevisionDojo provides formula flashcards with conditions built-in.
Step 5: Practice Time Management
AP Statistics exam = 3 hours.
- Section I (MCQ, 90 min): 40 multiple-choice, 2 min each.
- Section II (FRQ, 90 min): 6 free-response, ~15 min each.
In the last 48 hours, simulate timed conditions at least once. RevisionDojo has practice exams with pacing guides.
Step 6: Review Calculator Shortcuts
Don’t lose points on mechanics. Learn shortcuts for:
- 1-PropZTest / 2-PropZTest
- T-Test / 2-SampTTest
- Chi-Square Test
- LinReg T-Test
RevisionDojo includes step-by-step TI-84 and Desmos guides.
Step 7: Mindset for the Last 48 Hours
- Don’t panic if you don’t know everything. Strategy beats perfection.
- Sleep 7–8 hours. Cognitive performance drops with less.
- Eat balanced meals. No energy drinks before the exam.
- Use positive self-talk. Confidence = better performance.
Common Mistakes Students Make in the Last 48 Hours
- Cramming new material instead of reviewing.
- Pulling all-nighters.
- Ignoring calculator practice.
- Forgetting to review conditions for inference.
- Not practicing under timed conditions.
The RevisionDojo Advantage
RevisionDojo makes your last 48 hours structured and efficient:
- Formula sheets ready to print.
- Timed practice exams with pacing.
- Common mistakes logs to avoid easy point losses.

Frequently Asked Questions (FAQs)
Q: What’s the most important thing to review in the last 48 hours?
A: Formulas, inference conditions, and calculator shortcuts.
Q: Should I take a full practice exam the day before?
A: No. Instead, do a mini timed session (20 MCQs + 1 FRQ). Save energy for test day.
Q: Is it okay to memorize formulas last-minute?
A: Yes, but focus on application. The AP exam tests whether you can use formulas, not just memorize them.
Q: Should I review every unit equally?
A: No — spend more time on Units 5–9 (inference + regression).
Q: What’s the best way to calm nerves before the exam?
A: Light review, RevisionDojo’s exam-day checklist, and a good night’s sleep.
Final Thoughts
The last 48 hours before the AP Statistics exam aren’t about learning everything. They’re about strategic review, confidence-building, and avoiding mistakes.
- Review formulas and conditions.
- Solve timed practice problems.
- Refresh calculator shortcuts.
- Rest and recharge.
By combining this plan with RevisionDojo’s formula sheets, flashcards, and practice exams, you’ll walk into the test room ready to score a 5 on AP Statistics in 2025.
