Can wewe get held-back at Hogwarts?

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

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