How to get a 5 on AP Literature?

I took AP Lang as a sophomore and got my only 4, which made me sad as I consider English as one of my better subjects, yet I did the worst on that exam.

Now, as a junior, I want to prove to myself that I am good at English, and I really need a 5 on the AP exam. However, I know that AP Lit has one of the lowest 5 rates. Any tips/links/videos/other resources?
