SAT Sphere

Eight modules, 86 lessons, more than 10,000 practice questions and over 2,000 flashcards make up the SAT Sphere course, which splits its material between Math and Reading & Writing.

SAT Sphere is an online SAT prep platform that walks students through the exam content and lets them drill it with practice tests and past exams.

The study plans are the part that sets it apart from a plain question bank.

SAT Sphere uses AI to optimize a personalized plan, so you are not left deciding what to review next on your own.

Alongside the lessons you get a built-in dictionary and flashcards, which is handy for the vocabulary side of the Reading & Writing section.

The structure is straightforward.

You move through modules, break them into lessons, then test yourself on practice questions and older exams.

That works for a student who wants one place for both learning the material and checking progress, rather than stitching together separate free resources.

It is aimed squarely at the SAT, so it will not help with other exams.
