Question : What classes in college are considered English Composition I and English Composition II?
Answer : Are you asking for the actual course number? That's going to be different for every college. But the name of the course will usually be something close to English Composition - look at the primary English requirement in the lower division is you're not sure.
I've been to three different colleges, and they all required the same basic English Comp class. But I wouldn't be surprised if some schools have acceptable courses with specific themes.
