Finkster helped alot.
Anyways, watch out for be verbs. Avoid using them. (am, are, is, was, were, been, being, be, I’m, he’s, we’re, you’re, it’s, isn’t, aren’t)You'll have to change around sentences but your paper will benefit greatly.
Also, make sure you keep the same tense, and Avoid using "I". Other than that and what Finkster said, I'd say the paper is at LEAST C. Hopefully you have a completed MLA works cited page?
