Frequently asked questions

Do I have to answer all 50 questions at once?

No. Each set displays 25 General Chemistry or 25 Organic Chemistry questions at a time. Grade the visible section, then switch. Your answers remain selected while you move between sections during the same visit.

Are these official MCAT questions or scaled practice scores?

No. Both sets contain original, unofficial chemistry questions. Their scores are raw percentages for studying; they are not official AAMC scores or reliable MCAT score predictions.

What if I need help with the calculations?

Use the free Chemistry Math Review, then review General Chemistry I and General Chemistry II calculations.

Does this cover every discipline on the real MCAT?

No. This practice center emphasizes General and Organic Chemistry. The official MCAT also includes physics, biology, biochemistry, psychology, sociology, and critical analysis; consult the AAMC content outline for complete coverage.

How to use the two sets: Answer questions before viewing the explanations. For every missed question, identify whether the difficulty was a chemistry concept, unit conversion, math operation, mechanism, or experimental interpretation. Review that specific skill, then attempt the next set. These are original, unofficial chemistry-only materials. They are not official AAMC questions and do not predict your scaled MCAT score. Official section content also includes physics and biochemistry; see the AAMC section overview.
