Why students improve faster here

A patient teacher and a real exam, in one.

Most prep just scores you. We teach the method until it sticks — then test you under real pressure.

Questions

What you're probably wondering.

Which exams does Apex Altitude cover?
Live today: SAT. 23 more exams are in preparation — including AP subjects, UK qualifications, English proficiency tests and the international olympiads — and you can ask to be told when any of them launches. We only list an exam as available once it actually is.
Are the practice tests realistic?
Yes. Every live exam comes in four difficulty levels, with an exam-level version that mirrors the real test’s format and pacing, plus harder levels that push you above it. All questions are original and human-reviewed, and the bank grows regularly.
Can I try it before subscribing?
Absolutely — you can try a live question free, complete with the full step-by-step Practice-mode explanation, before choosing a plan.
What’s the difference between Practice mode and Test mode?
Practice mode shows one question at a time and gives a full beginner-friendly explanation with diagrams and video resources, whether you answer right or wrong. Test mode lets you choose difficulty, timing, and length, and sit the test under real conditions.
Do top-tier plans really include unlimited tests?
Yes — the Laureate and Summa plans include unlimited practice tests and questions across every live exam (SAT), subject only to fair-use limits described in our Terms. New exams are added monthly and are included at no extra cost.
