what classes would i have to take to major in english lit?

It really depends on the school and on your interests. There will likely be a course set of required classes covering "the canon." That might include major British and American authors, for instance. And you may have a required course or two on poetry. But beyond the core requirements, you'll then have room for electives. This is where your personal interests will take over and you'll be able to steer your degree in some direction you choose.

When I was an English major in undergrad, I was really interested in Asian philosophy, religion, and literature. So my "English" major consistently largely of authors who weren't English and texts that weren't originally written in English. So don't take the name too seriously. My last two years of college were all about "The Tale of Genji," "Journey to the West," and other non-English works of literature.

Whatever direction you choose, understand that an English major is going to be writing intensive. To me, that's one of its biggest strengths. The process of reading works of literature and writing about them draws in a lot of skills relating to writing (obviously), critical thinking, debate, and so on.

An English major is very broad. YOU have the task of and opportunity to shape it into something that really interests you. That process can be a lot of fun.
