How this works
- Work through each week in order — every week teaches a concept through a real-world scenario, with a live editor to practise in.
- Pass the short quiz and complete the practice exercises to unlock the next week.
- Along the way you'll tackle puzzle-style mini projects that combine everything so far.
- Finish the final mini project to unlock your level certificate — and the next level.
🌱 Level 1 — Beginner: SQL and Databases
What you'll build
Across this level you'll work with school-style tables — students, scores, classes — writing real SQL queries against them, from your first SELECT through JOIN and subqueries.
🌿 Level 2 — Intermediate: SQL and Databases
What you'll build
This level currently reuses Level 1's curriculum in full — the same 9 weeks and 2 mini projects, so the unlock chain and certificate work end-to-end for every level.
🌳 Level 3 — Advanced: SQL and Databases
What you'll build
This level currently reuses Level 1's curriculum in full — the same 9 weeks and 2 mini projects, so the unlock chain and certificate work end-to-end for every level.
