Can آپ get held-back at Hogwarts?

I think آپ can if آپ don't pass your OWL exams with a proper score. آپ might have to go back and study some مزید and re-take the test before آپ can اقدام on to the اگلے year. Thats just my guess.

Yes, آپ can be held back. There is an example. Marcus Flint was held back a year.
