Most MCAT prep is a dozen disconnected tools and a plan you fall behind on.

PrepCat is one complete prep instead. Your plan, your practice, your mistakes, your content, and your readiness, all in one place and all pointing at the same thing, your test day. So you always know you are on track.

From your first day to test day

Four steps, then the plan runs itself and adapts as you go.

1

Tell us your target and test date

Your goal score, your exam day, the days you can study, and a quick diagnostic. Two minutes, no card.

2

Get a plan built around you

A full schedule to test day, weighted to your weak sections and paced to the hours you actually have.

3

Log every mistake you make

Snap a photo of any question you miss. It reads it, files it, and turns it into review and recall.

4

Watch your readiness climb

An honest score projection that moves with what you really do, so you always know where you stand.

  • Weighted to your weak sections
  • Full lengths and review built in
  • Rebuilds in one tap

Every question carries its explanation with it, so review happens right where you answered.

Your mistakes, connected

Every mistake becomes a map

Two topics link when they are related, so a gap in one shows you the others it drags down. Hover a topic to see what it connects to, and why. This one is live, try it.

This is your prep, connected

Smart practice

Unlimited passages, aimed at your gaps

Fresh passages and questions generated around the exact topics you miss, with a Socratic hint that guides you instead of handing you the answer.

Chem/PhysGenerated for your weak spot

A biochemist prepares a buffer to hold pH steady during an enzyme assay. Which system best resists a change in pH when a small amount of acid is added?

A well buffered solution near its pKa
BA strong acid fully dissociated
CA salt of a strong acid and base
DPure water at neutral pH

Hint. A buffer works best when the weak acid and its conjugate base are both present in quantity.

The advisor

Talk to it like a tutor who has your plan

Ask for a lighter week, a vacation, or more practice questions. It makes the change for you and keeps you honest about staying on pace.

Your advisor

Knows your plan, and can change it

I have a wedding this weekend, can you clear Saturday and Sunday?
Done. I cleared both days and moved that content review into next week so you stay on pace for your goal.
Plan updated, still on pace

Deep guides and lessons

A full content library written for the MCAT, with the parts tied to your own mistakes flagged first.
