How it works

Crimsora is a teacher, not a textbook — one flat subscription for unlimited live tutoring sessions across every AP, SAT, ACT & school course.

  1. 1

    Meet your teacher

    Every course is taught by a named teacher with a real voice — the same one, every session, for the whole course.

  2. 2

    Learn by talking

    Your teacher teaches one concept at a time, out loud, on a whiteboard — you think along, they adapt. Come back for as many sessions as you want; there is no cap.

    A live tutoring session: two hand-drawn triangles on the whiteboard showing why triangles are rigid, above the triangle angle sum formula and a check-in question from the teacher
  3. 3

    Practice what matters

    Verified practice for every skill, with instant feedback — plus exam-style FRQs graded on real rubrics in AP courses. Unit quizzes adjust their difficulty to your mastery and cover your weak spots first.

  4. 4

    Fill your gaps

    Your teacher tracks weak spots and brings them back until they stick.

  5. 5

    See your progress

    A clear plan across every unit or domain, with mastery you can watch grow.

    The lessons tab: a teacher introduction from Mr. Sameer above a list of AP Statistics Unit 1 lessons, each with a Study button

The whole point is continuity: a teacher who knows you all semester, not a six-hour cram the weekend before the exam.
