Testing 1...2...3

Joey is diagnosed with a learning disability. He contemplates dropping out of high school, but changes his mind after talking to Caitlin. Caitlin tells him to stop feeling sorry for himself, because he's not the only one with a disability, because she has to deal with having epilepsy. Elsewhere, everyone cheats on a test. The teacher says since everyone gets an A, that test must not have been hard enough, so it won't count and he'd give everyone a harder test.
