Pass your DMV test faster, backed by science that tells you when you're ready.
Most DMV test preps throw questions at you and hope it sticks. DMV IQ uses spaced repetition to reinforce what you actually struggle with, plus a personalized readiness score so you know exactly when you're ready to pass, not just when you've run out of questions.
A system, not a quiz bank.
DMV IQ uses the same learning science behind medical board prep to make sure you actually retain what you study.
Active Recall
Every question forces you to retrieve the answer from memory — the single most effective way to build long-term retention.
Spaced Repetition
Questions you miss come back at scientifically optimal intervals. Questions you know well fade away. You study less and remember more.
IQ Readiness Score
A real-time probability estimate of passing your DMV test, based on your accuracy, coverage, and memory strength across all topics.
Based on research by Roediger & Karpicke (2006), Ebbinghaus (1885), and Cepeda et al. (2006). Learn more about our method
