The course pact.
Try the exercise by hand first. Notice where you get stuck — that's the
learning. Only then ask the grader (or the hint button) to tell you
whether you're right. The tool is a sparring partner, not an oracle.
Welcome
If this is your first visit, register a display name and you'll receive
a 4-character handle. Keep your handle (paper memo, QR, or URL); you'll need
it to come back from another device.
Data handling.
By registering you acknowledge that (1) your display name, 4-character
handle, and code submissions are stored by this app; (2) submitted code
is sent to AWS Bedrock (EU region; not used by AWS or the model provider
to train models) for automated grading; (3) your handle and submission
progress — but not your code — are recorded on an immutable chain for
post-course attestation; (4) data is kept until the end of the semester.
