Most schools require you to check your rights at the door as a stipulation for entry. Don’t agree, then don’t come.
My 18+ year old son asked be the other day if he could carry some Advil in his backpack in case he needed it. I informed him that the school has a zero tolerance policy on drugs and although he was a legal adult in every way like the teachers, he was unable to because he was a “student”. They set up these rules with good intentions but sometimes it does lose it in translation.
