An AI MCAT tutor that keeps months of content review on schedule

The MCAT covers a lot of science across a long test day. Leo turns your content review into a realistic schedule, explains passage questions step by step and uses spaced repetition so first-semester biochemistry is still there on test day.

Sample result

One explained concept question

The request
Why does a competitive inhibitor raise Km but leave Vmax unchanged?

Step by step

  1. A competitive inhibitor binds the active site, so it competes with the substrate.
  2. More substrate is needed to reach half of the maximum rate, so the apparent Km increases.
  3. At very high substrate concentrations the substrate outcompetes the inhibitor, so the enzyme can still reach the same Vmax.
  4. On a Lineweaver–Burk plot the lines cross at the y-axis: same 1/Vmax, different −1/Km.

A twelve-week outline

WeeksFocus
1–4Biochemistry and biology content; one CARS passage a day
5–7General and organic chemistry, physics; spaced review of weeks 1–4
8–9Psychology and sociology; first full-length practice test
10–12A full-length every week with a full review day after each; light review in the final days

What Leo does

  • Builds a study schedule across all four sections from your test date and weekly hours.
  • Explains passage-based questions in the science sections and the reasoning behind CARS answers.
  • Turns weak topics, such as amino acids, enzyme kinetics or fluid dynamics, into spaced-repetition review.
  • Reviews full-length practice tests: which misses are content, which are reading and which are timing.

What Leo won’t do

  • Does not do graded homework, take-home tests or anything your school requires you to complete on your own.
  • No real or leaked exam questions: it reviews the official practice tests you take and writes its own practice items. Confirm test dates, rules and accommodations with the AAMC.
  • Cannot guarantee a score. It shows you where the points are and keeps you practising.

How it works

  1. Share your schedule

    Test date, hours a week, coursework you have finished and any practice test scores.

  2. Get a plan

    Content review in blocks, with spaced review of earlier topics built in.

  3. Review full-lengths

    After each practice test, Leo sorts your misses and adjusts the next weeks.

Questions

How is the MCAT scored?

Each of the four sections is scored from 118 to 132, for a total between 472 and 528.

Can it help with CARS?

Yes. It works through passages with you and talks through why an answer fits the author’s argument, not just the passage’s facts.

Does it use AAMC materials?

Official AAMC practice materials are the closest to the real exam. Take them on the AAMC site and share your results, and Leo reviews them with you.

Is it medical advice?

No. Leo teaches exam content; it does not give advice about anyone’s health.
