As a forward-deployed engineer, I embedded in the exam-prep problem and shipped MeritMint end-to-end: courses, secure auth, and an exam engine that grades every question the instant a student hits submit.
Exam prep in Bangladesh runs on anxiety: students grind through mock tests, then wait days to find out what they got wrong — by which point the moment to learn from the mistake has passed. The feedback loop is too slow, and the tension never lifts. MeritMint closes that loop to zero: grade on submit, see the right answer beside your wrong one, learn it while it still stings.
A full-stack platform, shipped end-to-end — auth, payments, the exam engine, and the data layer that makes results and rankings hold up.
Register and login with bcrypt-hashed passwords and JWT sessions signed via jose. No third-party auth service to lock students out.
Per-question scoring the moment you submit — the correct option turns green, your wrong pick turns red, and the score lands immediately.
Every attempt is written to SQLite, surfaced on a per-student dashboard, and ranked on a per-exam leaderboard by score then time.
Three real course tiers with a purchase path that records the transaction and an expiry, gating exam access behind it.
This is the real interaction, recreated. Pick an answer — the engine grades it on the spot. The right option goes green, a wrong pick goes red, and the explanation lands immediately.
