About Zenith

Zenith is an independent test prep platform with original practice questions, timed practice exams, worked explanations, and an AI study tutor.

We build Zenith for students who want to know what to work on next. You can take a timed practice test where available, review the answers you missed, and turn those misses into a study plan.

What you can study

Zenith covers the SAT, ACT, AP and IB subjects, and other exams. Our SAT practice adapts between modules. The exam catalogue lists the formats available for each exam.

How we help you review

We write original practice questions and worked explanations. Summit AI can give hints, explain a step, and suggest lessons based on your practice.

Who runs the exams

Zenith is independent of the organizations that administer the exams. Our questions and practice scores are unofficial. You can contact Zenith to report an error or ask about your account.
