Using the workspace

Run, check, hint, reset

• Run previews your work in the browser on the visible dataset. It is not a grade.
• Check answer sends your work to the grader, which tests it on new hidden data.
• Hint reveals one idea at a time, starting with the gentlest. Pro members can also ask the AI tutor.
• Reset returns the exercise to its starting state after you confirm.

If a run is slow or stops

Runs and checks stop after a short time limit, and you can cancel them at any time. Your draft is never lost when a run is cancelled or times out. The first SQL or Python run downloads the runtime once, which can take longer on slow connections.
