You screwed yourself over by cheating, but try to go over the material previously learned and familiarize yourself with it as much as possible (take notes, etc)
study, study, study. some people even get to much anxiety during a test and fail because of that. i can't test because i always fail because i get to much anxiety. ask your teacher for more time to study or something? always best to just obtain what your learning and answer it yourself. school sucks but it's worth it!
