How a course works
Short lessons. Real checks.
Read a little
A short explanation with an example, written for students, not for experts.
Change it and run it
Edit the example code in the lesson and run it to see what changes.
Check, then solve
A quick check, then practice problems the judge checks on hidden tests.
Checkpoints and a final test
Pass them to finish the course and get your certificate.
Certificate
Finish a course, get a certificate anyone can verify.
Your name, the course, your final-test and checkpoint scores, the units and skills. A QR code and a public link let a recruiter or a college check it is real.
