A month of focused, structured prep is more than enough to earn a 4 or 5 on the AP Statistics exam — even if your in-class grade is shaky. This plan assumes ~1 hour per weekday and ~2-3 hours on each weekend day.
If you need to compress: see our 7-day cram plan or 3-day cram plan.
Week 1: Data Exploration + Sampling and Experiments
Goal: Master the descriptive statistics and study design vocabulary that show up on every FRQ.
| Day | Focus | Output |
|---|---|---|
| Mon | Diagnostic: take 25-question MCQ pretest | List your 5 weakest topics |
| Tue | Univariate displays + 5-number summary, IQR, outlier rule | 12 problems |
| Wed | Center, spread, comparisons, transformations of data | 10 problems |
| Thu | Scatterplots, , LSRL, residuals, | 12 problems |
| Fri | Sampling methods (SRS, stratified, cluster, systematic), bias | 10 problems |
| Sat | Experiments vs observational studies, confounding, blocking, blinding | 12 problems + 1 study design FRQ |
| Sun | Mixed practice + review missed problems | 20 MCQs |

Week 2: Probability + Random Variables + Sampling Distributions
Goal: Get comfortable with discrete and continuous distributions and the conceptual basis of inference.
| Day | Focus | Output |
|---|---|---|
| Mon | Probability rules, conditional probability, independence | 12 problems |
| Tue | Discrete random variables: , , combining variables | 10 problems |
| Wed | Binomial and geometric distributions | 12 problems |
| Thu | Normal distribution + normalcdf / invNorm | 10 problems |
| Fri | Sampling distribution of + Large Counts condition | 10 problems |
| Sat | Sampling distribution of + Central Limit Theorem | 10 problems + 1 random variables FRQ |
| Sun | Mixed Units 3-5 review | 25 MCQs |
💡 The key insight: Sampling distributions are NOT about a single sample's data — they're about the distribution of statistics across many possible samples. This conceptual move is what enables every CI and test.
Week 3: Inference — Confidence Intervals and Significance Tests
Goal: Lock in the 4-step framework and all 8 inference procedures.
| Day | Focus | Output |
|---|---|---|
| Mon | 1-prop -interval and 1-prop -test | 12 problems |
| Tue | 2-prop -interval and 2-prop -test | 10 problems |
| Wed | 1-sample -interval and 1-sample -test | 12 problems |
| Thu | 2-sample -interval and 2-sample -test | 10 problems |
| Fri | Paired -interval and paired -test (when to use which) | 10 problems |
| Sat | Type I/II errors + Power | 8 problems + 1 CI FRQ |
| Sun | 4-step FRQ practice — write out State, Plan, Do, Conclude verbatim | 2 timed FRQs |
⚠️ FRQ trap: When asked to interpret a confidence interval, NEVER say "the probability the true mean is in this interval is 95%." Instead: "We are 95% confident the true mean is between X and Y [units]." The 95% refers to the procedure, not this specific interval.
Week 4: Chi-Square + Regression Inference + Mock Exam
Goal: Finish the curriculum and build exam stamina.
| Day | Focus | Output |
|---|---|---|
| Mon | Chi-square goodness-of-fit | 8 problems |
| Tue | Chi-square test for independence/homogeneity | 8 problems + 1 chi-square FRQ |
| Wed | LinReg -test and CI for slope; reading computer output | 8 problems |
| Thu | Mixed multiple-choice mock: 40 MCQs in 90 min | Score and review |
| Fri | Full timed FRQ section: 6 FRQs in 90 min | Score with rubric |
| Sat | Full timed mock exam (3 hours total) | Honest score |
| Sun | Targeted review of weakest mock topics + light FRQ work | Don't cram new material |
Daily habits throughout the month
- Spaced repetition flashcards for inference procedures and conditions — 5 min/day.
- One FRQ per week minimum from a past College Board exam — score with the rubric.
- Track missed problems in a single notebook by topic. Review weekly.
Calculator routine (build into Week 2 onward)
Become fluent with these on your specific calculator (TI-84, TI-Nspire, etc.):

The night before & morning of
- Skim the last-minute review checklist.
- Review the FRQ template phrasings.
- Sleep 8+ hours.
- Eat breakfast with protein and slow carbs.
- Pack: 2 sharpened #2 pencils, blue/black pens, approved calculator, fresh batteries, photo ID.
Final word
A 4-week plan rewards consistency more than intensity. Show up every day, even if it's just 30 minutes. The students who score 5s aren't the ones who pull all-nighters — they're the ones who logged 25 quiet sessions in a row.
