Move from diagnosis through targeted review and timed sections, with the timing, calculator, and task-verb decisions that earn the points.
Eight weeks of AP Statistics, one week at a time
Each week names the AP Statistics units you work on and one thing you finish and keep. Tick a week off when the deliverable exists, not when the time is up.

What you finish that week
Done
Week 1
Diagnose and rebuild data description
One-Variable Data and Collecting Data
An error log plus ten distribution descriptions using shape, centre, spread, and outliers.
Week 2
Study design and sampling
One-Variable Data and Collecting Data
A written comparison of random sampling and random assignment, with what each one permits you to claim.
Week 3
Probability and random variables
Probability, Random Variables, and Distributions
Twenty probability problems, half solved with a simulation description instead of a formula.
Week 4
Sampling distributions
Probability, Random Variables, and Distributions
Sketch and label the sampling distribution of p-hat and x-bar, including the standard error for each.
Week 5
Inference for proportions
Inference for Categorical Data: Proportions
Five complete four-step answers: hypotheses, conditions, calculation, conclusion in context.
Week 6
Inference for means
Inference for Quantitative Data: Means
Five more four-step answers, including one paired and one two-sample situation.
Week 7
Regression and choosing the right procedure
Regression Analysis
A decision chart that maps a scenario to the correct test, plus five slope interpretations in context.
Week 8
Full timed rehearsal
All five units
One complete timed exam, then rewrite every free-response answer to rubric standard.
AP Statistics exam strategy
A plan tells you what to study. This tells you how to spend the exam itself. Work these decisions into every timed week above, so exam day is a rehearsal rather than a first attempt.
AP Statistics timing: what one question is worth in minutes
Work out your pace before exam day so you never discover it during the exam.

Questions
Pacing note
Multiple choice
1 hour 30 minutes
42 questions
About 2.1 minutes each. Reading the scenario is most of the work; the arithmetic is usually small.
Free response
1 hour 30 minutes
4 questions
About 22 minutes per question. These are long, multi-part scenarios - read all parts before writing part (a).
Calculator and reference rules for AP Statistics
Calculator rules change from section to section, and they are different on every AP exam. Practice each section under its own rule.

What that means for your work
Multiple choice
Graphing calculator with statistics functions
Use it for normalcdf, invNorm, and binomial probabilities instead of the tables when speed matters.
Free response
Graphing calculator with statistics functions
The calculator gives the number; the rubric pays for the name of the procedure and the conditions.
Provided for the whole exam
Formula sheet and tables
Formulas and the normal, t, and chi-square tables are given. Do not spend study time memorising them - spend it on when each applies.
Free-response points are written for a specific verb. Answer a different verb and the work can be correct and still score zero.
Task verbs used on AP Statistics free-response questions
If the prompt says
The point is earned by
State the hypotheses
Write them about parameters, using mu, p, or beta. Hypotheses written with x-bar or p-hat lose the point automatically.
Justify your choice of procedure
Name the test or interval AND check each condition with the numbers from this problem, not a generic list.
Interpret the confidence interval
'We are 95% confident that the true [parameter in context] is between ... and ...' Anything about 95% of the data or a 95% chance is wrong.
Describe the distribution
Shape, centre, spread, and unusual features - all four, all in context, with units.
Explain whether the conclusion is reasonable
Compare the p-value to alpha, then answer the researcher's actual question in their words.
How students lose AP Statistics points
These are specific to this exam. Read them again the night before.
Never write 'accept the null hypothesis' or 'this proves'. You either reject or fail to reject, and neither proves anything.
Random sampling lets you generalise to a population; random assignment lets you claim cause and effect. Claiming causation from a survey is a guaranteed lost point.
Conditions are graded separately from the computation. A perfect p-value with no condition check scores well below a rough p-value with the conditions verified.
Every conclusion needs context. 'Reject the null' is half an answer; 'there is convincing evidence that the mean commute time is longer than 30 minutes' is the whole one.
AP Statistics priorities to protect every week
A useful plan is course-specific. Whatever else a week contains, keep time for the content and response habits that decide AP Statistics scores.

Questions about AP Statistics eight-week study plan and exam strategy
How should I split eight weeks of AP Statistics revision?
Week 1 is “Diagnose and rebuild data description” and you finish it with one thing you keep: an error log plus ten distribution descriptions using shape, centre, spread, and outliers. Week 8 is “Full timed rehearsal”. Start at the week that matches the time you have left, not at week one.
How should I pace myself on the AP Statistics exam?
Multiple choice — About 2.1 minutes each. Reading the scenario is most of the work; the arithmetic is usually small. Free response — About 22 minutes per question. These are long, multi-part scenarios - read all parts before writing part (a).
What does “State the hypotheses” mean on the AP Statistics exam?
Write them about parameters, using mu, p, or beta. Hypotheses written with x-bar or p-hat lose the point automatically. Answering a different verb can be mathematically correct and still score zero.
What is the biggest scoring trap on the AP Statistics exam?
Random sampling lets you generalise to a population; random assignment lets you claim cause and effect. Claiming causation from a survey is a guaranteed lost point.
