Do not, I repeat DO NOT, tell them anything about the computer admin or w/e thing. If something happens they'll be first to blame you for any reason. Serve the detention, after 2 or 3 times of detention, go talk to the dean and be like, "Look, this detention thing isn't working. I've done everything humanly possible for me to be in that classroom on time, and you should be able to see this by now. (Now this part is only if you're making really good grades) Study hall isn't helping me much either. I learn a certain way, and I can't concentrate when I'm in a classroom full of students. *Insert more witty lines here*"
Eventually the teacher watching you for 3 hour detention on Saturday will get tired of it.
You have to act like you know what you're doing, and they'll look as you as an adult.
