I genuinely thought my school was absurdly bad, but this is just a whole other level of forgeted.
That's absolutely unfortunate, sorry to hear that mate, I'm also really into video production and stuff like that and would come up with the highest quality video in the entire class time and time again, only to have my grade be taken down because it was edited partly from home, or some other requirement being exceeded too much, or what have you, but never have had a teacher be this negligent.
Hope talking to him about it goes over well, that's a seriously stuffty thing to do.
