Self-check

Check your own understanding as you work through the module. Nothing here is marked or uploaded. Once you enable local progress, answers and results stay in this browser profile. A wrong answer tells you which misconception you have hit.

Made with AI assistance and reviewed and verified by a human instructor before release. See AUTHORS.md for credits.

Prefer to work in a terminal? The same checkpoints run as python3 selfcheck.py run all in course/lab/. The two routes are equivalent — use whichever suits you.

Progress belongs only to this browser, profile and device. Private browsing, clearing site data, removing the profile, a browser reset, storage eviction or device loss can erase it. Keep a separate copy of work that matters.
