A reasoning exam with formulas — the FRQs are graded almost entirely on writing.
AP Statistics is graded less on whether you reach the correct numerical answer and more on whether you state assumptions, name the procedure, communicate the conclusion in context, and link the conclusion back to the original question. Many students with strong math instincts under-score because they never wrote a complete inferential conclusion.
Our practice FRQs are scored against the official AP rubric line-by-line, with every 'state, plan, do, conclude' step called out separately so you can see exactly which sub-step would be marked partial credit by a real reader.
