## What is So Smart DRE?

So Smart DRE is the study companion for Drug Recognition Expert certification. Whether you're preparing for pre-school, final exams, or staying sharp on the job, this app puts the full DRE matrix and study system in your pocket.

FEATURES:

— Countdown Dashboard
Track your days to pre-school and final exam. See your daily progress at a glance with items checked today.

— Matrix Drill
Practice the full 63-cell DRE symptomatology matrix — all 7 drug categories across 9 clinical indicators. Tap a cell, pick the expected finding, and get instant feedback. Track your accuracy and chase a perfect clean run.

— Smart Review
An adaptive 15-item session weighted to what YOU get wrong. Mixes matrix cells, quiz questions, and flashcards. Get it right and it fades; miss it and it keeps coming back.

— Quiz Mode
Multiple-choice questions weighted toward your misses. Choose 10 or 20 questions per session. Instant feedback with explanations.

— 12 Steps
Learn the 12-step DRE evaluation procedure, then test yourself by putting them in order from memory.

— Flashcards
Multiple decks covering matrix mnemonics, clinical tells, vital sign ranges, and drug durations. Swipe through and grade yourself.

— Say It Out Loud
Recite test-administration procedures, the 12 steps, or any flashcard answer and the app checks your wording against the NHTSA manual, marking exactly what you left out.

— Progress Tracking
See your runs, weak spots, and quiz history. Identify which cells and categories need more work.

— NHTSA Manuals
Quick access to every session's manual content as a PDF, right from the app.

— Sync Everywhere
Same account, same data on every device. Sign in on the app and pick up right where you left off on dre-study.pages.dev.

No ads, no subscription, and nothing locked behind a paywall.

Built by a deputy for deputies, troopers, and officers pursuing DRE certification.

INDEPENDENT STUDY AID
So Smart DRE is not affiliated with, endorsed by, approved by, or sponsored by NHTSA or the International Association of Chiefs of Police. Session manuals are the publicly published NHTSA/IACP Drug Evaluation and Classification curriculum, split into per-session files for easier study, with no changes to the text; links to the official NHTSA documents are provided in the app. Nothing in this app confers DRE certification -- certification comes only from the DEC Program through your agency.
