Administrator accidentally deleted?

I unknowingly deleted my administrator. I bought the laptop from school because I was in a laptop class and now I'm not at school any more. The only administrator is my old teacher, but I do not know his password. I forgot to delete my admin. What can I do? Can the Applestore set it up so that there's only one admin left? Because I can't do some functions now. Have a MAcbookAir

An admin can only be deleted via another admin account and not with a normal user account

So I somehow managed XD

The school bought a laptop… öhhmmm… Ne is clear.

Schools are allowed to do so easily.

I've already tried that. It does not work

Do you mean Applestore could help me with that?
