That is very strange. Was there a meeting with your teachers and your parents? Usually, there's an Individual Education Plan written up, specifying what support they're going to give you, and what accommodations, if any. You should know about whether you're going to have a support teacher, or extra time on exams, for example. That's in public schools in the US. If you're in a private school, they may not do anything for you. Have you asked your parents?
