I did my homework but it still shows as not done

There are two versions of this, and they have opposite fixes.

1. You answered everything but never pressed Finish course #

This is the common one.

While you work, the screen tells you "Your answers are saved as you go — on this device and on your account." That is true, and it is why the lesson feels finished. But a saved answer is not a handed-in course. Nothing reaches your teacher until you press Finish course.

So you close the tab, come back later, and the course is still on To do — with your answers still in it.

The fix: open it again and press Finish course at the top. Your answers are all still there.

2. You pressed Finish course too early #

Carna does not stop you finishing with questions left blank. It hands the course in exactly as it is, and every blank scores zero. On the results screen those questions read "Not answered" next to the correct answer.

If you answered 3 questions out of 22 and finished, the course is complete and your score is low. It is not a bug and it is not stuck.

The fix: before you press Finish course, open All questions at the top. It says "3 of 22 answered" and marks every gap with "Not answered yet — tap to go there". Tap each one, answer it, then finish.

Make that your last step every time. It takes five seconds and it is the whole problem.

After you finish #

The course moves to the Completed tab with your score and the date, like 5% SCORE · SUBMITTED OCT 10. Review opens it again, as many times as you like — going back over it does not undo it and does not change your score.

Whether you can see the right answers depends on what your teacher chose: straight away, or only after the due date.

If it is still wrong #

If you pressed Finish course, the course is in Completed, and your teacher still says it is missing, write to support with your school's name, the name on your account and which course. Those three are what we need to find the record.
