DAT Prep Roadmap
A 20-session, self-study roadmap for the Dental Admission Test — from the basics up.
A project built directly by Ted TH Lee.
Why I built it
The DAT packs biology, general and organic chemistry, PAT, quantitative reasoning, and reading comprehension into one exam, so studying alone makes it hard to know where to start and how much to do. This puts study, review, and mock exams on a single roadmap weighted like the real test — nothing but a browser needed.
What it does
- 20-session curriculum in three phases (foundations → core → advanced), weighted like the real exam, with a dental-arch progress tracker.
- Each session: concepts (English terms + Korean explanations) → flashcards → quiz with instant grading and explanations.
- PAT lab — procedurally generates unlimited figure problems (SVG) across all six types: keyhole, TFE, angle, hole punching, cube counting, pattern folding. Timed drills included.
- Spaced-repetition review (SM-2) and a wrong-answer notebook that fills itself and clears as you re-solve.
- CBT mock exam — full-length (280 questions / 4h15m) or half, with per-section timers, question palette, review marking, and an estimated 200–600 scaled score.
- Study stats — accuracy by subject, last 7 days, weak sessions, mock-exam score trend.

How it was built
A single-page app in plain HTML, CSS, and JavaScript with no build step. There is no server and no account: progress, quiz logs, wrong answers, review intervals, and mock-exam results all live in the browser's localStorage, so it starts instantly and picks up where you left off in the same browser.
The content spans 20 sessions, 191 concepts, and 394 static questions (biology 120, general chemistry 72, organic chemistry 72, PAT 30, QR 40, RC 10) plus three long reading passages (50 questions) for the mock exam. PAT additionally has a generator that keeps producing new figure problems per type. Every question was independently re-solved blind and compared against the answer key; the one error that surfaced was fixed.

How you use it
Pick a session on the dashboard
Tap the next session on the dental-arch tracker. Going in order from phase 1 is recommended.
Concepts → flashcards → quiz
Read the concepts (English terms with Korean explanations), lock them in with flashcards, then check with a quiz. Misses go to the wrong-answer notebook automatically.
Weave in review and PAT drills
The review tab resurfaces concepts on their memory schedule. In the PAT lab, practice freely by type or run a 15-question / 8-minute timed drill.
Take a mock exam
Sit a full or half CBT, get section-by-section grading and an estimated scaled score, then use the stats tab to find weak subjects and go back to studying.
Questions
- Do I need an account or payment?
- No. It works without login and saves progress in your browser — clearing browser data clears progress too.
- Can I practice PAT with actual figures?
- Yes. All six types are procedurally generated as SVG, so problems don't repeat. Exam-faithful rendering (e.g., TFE hidden lines) is still being refined.
- How accurate is the scaled score?
- The 200–600 conversion is an estimate; calibrating it against real data is a next step.
- Is this official ADA material?
- No. It's a personal project unaffiliated with the ADA, and every question is original.
