The short answer
Each week ends with a short check that passes at 40%. You can retry as often as you like and your best attempt counts. A final quiz with the same pass mark finishes the internship.

Short final quiz on a 4-week plan
Checks are there to help you learn, not to catch you out.
- Every week has a short week check. It passes at 40%.
- You can retry as many times as you like. Your best attempt counts.
- The internship ends with a final quiz, which also passes at 40%.
- On a 4-week internship the final quiz is a short one covering weeks 1 to 4 (10 questions).
An internship completes itself once every card is done, every week check is passed and the final quiz is passed. Your certificate and documents are then issued, each on its own date (see How do I get my internship certificate?).
If a check will not pass
- Open the week again and read the cards you missed.
- Look at your last answers: the page shows what you picked.
- Ask the AI mentor about the topic.
- Try again. There is no limit and no waiting time.
Practice tasks in the 3D lab are separate from the checks and are optional.
