SQL Quest

Lessons, hints, explained solutions, the in-browser PostgreSQL editor and practice answer checks in your browser are available. Graded assessments, recorded progress from answer checks and new certificates aren't available yet.

Assessments

Measure what you can actually do

Questions are drawn on the server from larger banks, your answers are graded only when you submit, on the lesson data and on a hidden copy with different rows, and scores are stored with server timestamps. Assessments are open-book and not proctored.

Not available yet. Graded assessments aren't available yet: they need SQL Quest's server-side grader, which is switched off until its security review is complete. You can still practise every lesson and check practice answers in your browser.
