## What DMV IQ Is

DMV IQ helps users prepare for their state's written driving knowledge exam (DMV, DPS, BMV — terminology varies by state). It covers three vehicle types:

- **Car (Class D/E)** — Standard driver's license / learner's permit
- **CDL (Class A/B/C)** — Commercial Driver's License for trucks, buses, and hazmat vehicles
- **Motorcycle (Class M)** — Motorcycle endorsement / permit

The platform provides 7,456+ practice questions sourced from official state Driver Handbooks and current statutes. Every question includes a hint, a brief explanation, and a detailed explanation with handbook references.

### Learning Science
DMV IQ is built on three evidence-based learning principles:

1. **Active Recall** — Every interaction is a question, forcing retrieval practice rather than passive re-reading.
2. **Spaced Repetition (FSRS-5)** — Questions the user gets wrong resurface at scientifically optimal intervals.
3. **IQ Readiness Score** — A proprietary 0-200 score that estimates pass probability.
