High School English Course Selection?!?!?

Ok, so for junior level english at my school, you can either go to AP English 3, or Brit Lit. AP is weighted, but its expected that you will get a 'B' or 'C' (the teachers rarely give A's). Brit Lit isnt weighted, however, I know I can get an A in that cl. I cant decide for the life of me. Any advice?
