AP Prep: Practice & Score

Turn AP® Biology practice into real score gains. Every multiple-choice question comes with a full explanation, every free-response answer is graded point-by-point against its rubric, and a live 1–5 estimate shows where you stand — updated as you practice. WHY IT WORKS • FRQ grading, point by point — type your free response and see exactly which rubric points you earned and which you missed, with a model answer for each part. • Real explanations on every MCQ — why the right answer is right, why each distractor is wrong, the common trap, an exam tip, and a memory hook. • A 1–5 estimate you can trust — your accuracy is weighted by each unit's share of the real exam. It's a practice estimate, not an official score. • Timed mock exams — full or quick, both sections, scored 1–5 like test day, with a point-by-point review. • A mistake book that works — every question you miss lands here on its own; re-do it and it clears when you get it right. WHAT'S INSIDE • MCQ practice by unit and topic, with a question map and a four-function calculator • Free-response practice with rubric-by-rubric grading and "practice the missed point" drills • Full and quick mock exams with section timing and a 1–5 result • Mistake book with per-question review • My AP — set each subject's exam date and target, and track your estimate FREE & PRO Start free, no account needed.
