Built for a different job.
Khan Academy, textbooks, and $80/hr tutors are all genuinely useful. None of them let you drag a variable and watch the curve move.

Best pairing: use Simistry for the “I need to see this” moments, keep the textbook for reference, and save the tutor for the two topics you actually can’t crack.
Backed by a real score guarantee
Lifetime members who put in the work and still self-report a 1 or 2 on the real exam get 50% back, verified against a College Board score report, with no hoops beyond that.

The questions students and parents actually ask before upgrading.
Free includes 12 full simulations, live preview of every locked sim, the interactive AP reference sheet, and light/dark themes, no card required. Pro adds the full catalog, FRQ practice with rubric self-scoring, the mastery dashboard, and unlocks the Study Guide and Concept Atlas.
Same Pro features either way. Monthly is month-to-month and easy to cancel; Yearly is the same plan billed once for the whole exam season, which works out cheaper per month and is what most students pick going into the fall.
Pay once, use the platform forever. If you buy 60+ days before your exam, log 40+ hours across at least 6 of 9 units, and still self-report a 1 or 2 on the real AP Chemistry exam, we refund 50%, verified against your College Board score report. See the full terms on the guarantee page.
