The SAT prep that feels polished and stays completely free
PrepSt is a beautifully designed SAT prep platform built by students for students. It adapts in real time, feels polished from the first click, and costs you absolutely nothing.
Why most SAT prep still feels broken
Students do not need more noise. They need smart practice, clear progress, and a platform that actually feels made for them.
Wasting hours on generic practice
Traditional prep books give everyone the same questions. You're either bored with easy stuff or overwhelmed by things you're not ready for.
Using prep that was never built for students
Too many tools feel corporate, generic, and disconnected from real student routines. You need something that understands how students actually study.
Forgetting what you learned
You study for weeks, but when test day comes, you can't remember half of it. Traditional methods don't account for how memory actually works.
Losing motivation fast
Endless practice tests without seeing progress kills your drive. Most students give up before they ever see real improvement.

Hit Target Score
I was stuck at 1180 for months using Khan Academy. PrepSt figured out I was rushing through easy questions and overthinking hard ones. Within 6 weeks, I hit 1550. Crazy.
Sarah K.
Yale '28
The predictive analytics are insane. It told me I'd score 1570-1590 two weeks before my test. I got 1580. It's like having a crystal ball.
Marcus T.
Stanford '27
I started with a 1050 and honestly thought I'd never break 1200. The adaptive practice made me actually enjoy studying. 430 points later, I'm going to MIT.
Emily R.
MIT '28
Went from 1280 to a perfect 1600. The vocabulary builder alone was worth it. I actually remember words now instead of cramming and forgetting.
