What's Inside

The practice. The system. The teacher.

Every part of PrepZone has been carefully designed to give you the tools and resources to reach your top score. Here's what you get.

1,690Qs

Real SAT questions

Official College Board questions, tagged by skill and difficulty. Not lookalikes. Not AI-generated. The actual test material, organized so you practice what you actually need.

6Levels

Earn the next level

Starter to Elite. You don't get dumped into 1,690 questions and told to swim. You climb level-by-level, Math and Reading on independent tracks. Hit the mark and you move up.

1Teacher

Who'll know your name

I track every student's progress. You move up automatically when you hit the mark, and I still see the whole picture. If you're stuck, I see it. If you're crushing it, I see that too. This isn't a faceless app.

3Weeks

TestReady for the final stretch

Start 21 days before your test. Week 1 is Foundations: six short untimed units to get your accuracy back. Week 2 is Pacing: timed half-modules that build your sense of the clock. Week 3 is Full Modules: 30 full-length modules from official College Board practice tests, timed like test day. Runs on an iPad or computer.

1A Day

Why PrepZone

What makes this different.

It feels like the real test

The interface is built to match Bluebook — the actual digital SAT platform you'll use on test day. Two-pane passages, Desmos calculator, mark-for-review flags. Test day shouldn't be the first time you see the format you're tested in.

I see what you're missing

The platform tracks first-attempt accuracy on every question. When students miss the same problem over and over, I see it — and I record a targeted video explanation that lives right inside the workbook. Like sitting across from me at a desk.

Your effort actually pays off

Most students put in the time and don't see scores move. That's not because they're not working — it's because the work isn't aimed right. The whole point of this platform is to make sure every hour you spend pushes your score up.

You're not doing this alone

PrepZone is the practice platform of PrepZone Skool — a community of students prepping for the same test. You'll learn from others who are a few steps ahead, stay motivated when the work gets hard, and end up helping someone else once you've got it figured out. Members also get a study plan built from their scores, the weekly review (workbooks plus live Math on Tuesday and R&W on Thursday, recorded), and a report on exactly where they're losing points.

Who Built This

Hi, I'm Miguel. MIT engineer. SAT teacher.

I grew up in the Rio Grande Valley and graduated from MIT with a degree in mechanical engineering. Before MIT, I was also accepted to Stanford, Columbia, Princeton, and Rice — the schools my SAT score opened the door to. I know the strategies in this platform work because they're the same ones I used myself.

For the last ten years I've been teaching the SAT to hundreds of students. I've watched what works and what doesn't. Most students put in real time and effort and don't see their scores move — and the problem is almost never the work. It's that nothing is telling them whether the work is aimed right.

PrepZone fixes that. It tracks your progress so I can keep you on the path, and it lets me drop targeted video explanations onto the questions students miss most — so when you're stuck, you get the same explanation you'd get if we were sitting across from each other. Wherever your score is today, the tools here will push it up.
