The SAT reuses the same question patterns, test after test. We analyzed hundreds of real released questions to name those patterns — then built a prep system that teaches you to recognize them before you touch the answer choices.

How it works
Not just the topic — the trap. You learn to spot the setup before you read the choices, which is the difference between knowing the math and finishing on time.
Interactive lessons
Each lesson teaches a skill at three difficulties. Read the walkthrough, follow a worked example line by line, then answer three questions written for that exact explanation. The next difficulty unlocks when you've done the practice.

Move the smaller x-term across, then peel off the constant, then divide by the coefficient.
Adaptive diagnostic
A full-length adaptive diagnostic routes you to an easier or harder second module based on how the first went — the same structure as the real digital SAT. You get a score range, your strongest and weakest skills, and a study plan built from them.

Mistake review
Every wrong answer lands in your error notebook, grouped by the pattern behind it, and resurfaces on a spaced schedule until you stop missing it. An AI tutor is attached to each one if the written explanation isn't enough.

You stopped at 4x = 20. That's 4x, not x — divide both sides by 4.

The approach is built on analysis of real released College Board questions, but the questions you practice are original — written for this platform and tagged with the pattern each one tests. Reproducing College Board questions would be a copyright problem, so we don't.
Most prep sorts questions by topic. We sort them by the mistake they're designed to provoke, and every wrong answer choice is tagged with the specific error that leads a student to it. That's what makes the explanations useful rather than a restatement of the answer.
After you answer a question you can ask follow-ups about that specific question — why a particular choice tempts, or how to approach the type next time. It has the question, your answer, and the explanation in context, so you don't have to restate anything.
On the Accelerator plan and above, a parent gets a text report after each study session with real numbers — including the sessions that were too short to count for much. Parents can also see the diagnostic report and study plan.
Yes. Everything works in a mobile browser, though full-length practice tests are much easier on a laptop — they run to 98 questions with official timing, and that's a long time on a phone.
A placement test maps your starting point, then builds a week-by-week roadmap around the skills costing you the most points.
