Igloo Study

Test-taking platform for Igloo Study, a tutoring service I run. Students take placement/level tests in the browser; I upload, edit, and review tests from an admin dashboard.

Try the tester, it talks to the live API, so go easy.

This is a real product with real users, not a demo. The classroom side, Igloo Classroom, lives in a separate private repo (code on request).

Parts

Folder	What it is
igloo-backend/	Express API + PostgreSQL. Tests and submissions are stored in Postgres; test PDFs/images go to Cloudinary. Admin routes are protected with an x-admin-key header.
igloo-admin/	Admin dashboard, log in, upload a test (PDF or image), edit questions/answers, review student submissions.
Igloostudy-tester/	The student-facing tester, pick a test, answer, submit.

API surface

GET  /api/tests, /api/tests/:id          public: list/fetch tests
POST /submissions                         student submits answers
GET  /admin/tests, /admin/submissions     admin: manage tests & review submissions
POST /admin/tests/upload                  upload a test file (multer → Cloudinary)

Run locally

cd igloo-backend
npm install
cp .env.example .env     # DATABASE_URL, ADMIN_KEY, CLOUDINARY_*
psql "$DATABASE_URL" -f sql/schema.sql
npm run dev

Then open igloo-admin/index.html and Igloostudy-tester/index.html (any static server; config.js points them at the API).
