What the video shows

• Full mock exams — both sections, four modules, 98 questions, with the ten-minute break. Reading and Writing runs 32 minutes a module, Math 35.
• A bank of 2,079 questions in the real digital SAT format, each tagged by topic and College Board score band.
• Practice by topic at a difficulty band you choose, from five questions to fifty.
• A report on your working — what you highlighted, what you eliminated, where you changed your mind, and how long each question took.

Is it really free?

Yes. The mocks, the question bank, practice by topic and the adaptive diagnostic all work without an account. An account only syncs your progress between devices. There are no adverts and nothing is sold. More on how it works in the articles, including what your working reveals that your score doesn't.
