Is Kramizo really free for US Common Core US Physics 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 US Physics questions aligned to the US Common Core Common Core syllabus?

Every question is written against the published US Common Core Common Core US Physics 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 US Common Core past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.
