(Did) you get any sleep last night? is better :)

Correct! "Haven't got much"/"haven't got many" means the same as "I have very little" (Maybe it's enough for you today, but not for the whole week, or you're worried that it might not be enough for a certain recipe. These are just other examples). "Haven't got any" means Zip! Zero! Zilch! :) None at all!

I'm not sure I've ever heard the phrase "off the point" to be honest :) Beside the point definitely. On point / off point I've heard - rather slang, but a very different meaning (perfect / not quite right)

Hey! I'm not Hungarian, but I'm also learning and so I'll try to give a hint here. I think it's easiest to explain these verbs by comparing them with the active verbs, because a lot of them come in pairs anyway: -ít vs. -ül/ul -ít tanít , barnít , csoportosít Here the subject is changing someone or something. These -ít verbs require an object. to teach, to make brown - tan , to group - to put into a group A tanár tanít valakit. A nap barnít az embert. A tanár csoportosította a diákjait. -ül/ul tanul , barnul , csoportosul the subject itself is learning , becoming brown or tan, getting themselves together in a group A diák tanul. Az ember barnul a nap alatt. A madarak csoportosultak. Sorry for the silly examples and please excuse any mistakes, but I hope the -ul verbs make more sense now :) :)
