Ap Literature?

English is my second language. I love reading and writing, and I thought taking this class on my senior year next year is a great idea. Now that I realize it, I feel like I will be the dumbest kid in that class since I am not really good at english yet. I had an A plus in my english CP1 class though and thought I will be prepared for AP Literature.

I also started the Foster book and it's driving me insane. I don't understand a thing, it's too much information. I want to just normally read one summer reading just like what I did from sophomore year and last year.

But I'm sure my parents will be disappointed in me. I'm just worried this class will lower my GPA and stress the fuck out of me.

Any advices?
