Is Kramizo really free for AP Calculus AB students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Are the Calculus AB questions aligned to the AP CSEC syllabus?

Every question is written against the published AP CSEC Calculus AB syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real AP past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.
