How do you get a 5 on the ap english exam?

I try really hard to do well in ap english right now I have an 89.76 in the class. My english teacher grades hard and I get other teachers to check my work especially the english professors and they all say that I have a gift of writing he gave me an 80% on both of my animal farm essays which i think is unfair. Plus, i hAD AN ADVANTAGE BECAUSE I READ IT IN 10TH GRADE TOO. hE KNOWS iM A GOOD WRIT IER WHY WONT HE GIVE ME ADVICE WHEN I ASK HIM WHAT I NEED TO IMPROVE ON AND PLUS HE ACTS WEIRD WHEN i AM TALKING TO HIM SEEMS NERVOUS. sorry for the caps I m not shouting. thx!
