Hello! Don't worry about GCSEs for now if the college aren't. They'll get you maths and English while you're there anyway, and those are the ones you'll need in the future. Look into potential university courses that interest you and look at the entry requirements. If this course will get you in and you think you'll enjoy it, go for it. As for contacting tutors etc, they'll go over all of that with you. You don't learn a lot about college in school, so everyone joining will be in the same position as you. They won't know anything either. You'll either be given or be able to ask for email addresses of tutors, and you'll obviously have regular lessons with them. Before you join, ask to be put into contact with their student services/disability team. They'll make sure support is in place for when you join, and they're really good if you need someone to talk to as well
