Learn MCAT like you have a private tutor.

Ask out loud or type. Your teacher talks with you, listens, draws on the whiteboard and explains it a different way until it clicks — day or night. Free to start.

Km goes up, Vmax stays the same — which inhibitor?
Noncompetitive?
Competitive — enough substrate outcompetes it, so Vmax is unchanged.

Why our MCAT quality is different

  • Real MCAT structure and timing — Chemical and Physical Foundations, Critical Analysis and Reasoning Skills, Biological and Biochemical Foundations, Psychological, Social, and Biological Foundations, with the official section order, question counts and time limits (6 hours 15 minutes, 230 questions).
  • Original, carefully reviewed questions — written for the MCAT’s style of reasoning, never copied from official tests.
  • Every answer explained — why the right answer is right, why each wrong one is wrong, and a tip to remember it.
  • Score reports that teach — estimated 472–528 scores, skill breakdowns and time per question.
  • Teaching that adapts — beginner to top scorer, seven teaching styles, real-life examples, diagrams and mnemonics.

Questions

Is my teacher a real person?

No. Your teachers are AI-powered characters shown with AI-generated portrait images and synthetic voices, designed to teach like a patient private tutor. They’ll always tell you so if you ask.

Are these real MCAT questions?

No. Every question is original and written to match the official format of the MCAT. We are not affiliated with or endorsed by the Association of American Medical Colleges (AAMC).

Is this medical advice?

No. Clinical questions, explanations and lessons are for exam preparation only — not advice for real patients.

How accurate are the scores?

Scores are estimates based on your answers. They’re useful for tracking progress, but no practice test can predict your official score exactly.

Is MCATPractices part of MedWorldHub?

Yes — mcatpractices.com is the MedWorldHub site for the MCAT. Preparing for more than one test? See usmlepractices.com (USMLE), dattests.com (DAT) or the hub for all eight exams at medworldhub.com.

Can I cancel Pro?

Yes — cancel any time from your account page. You keep Pro until the end of the billing period.
