I am a Junior in High School and currently taking English 11 AP. It's my worst subject but I decided to take this class because I need to get better at it, and having this challenge definitely motivates me. However... I feel like no matter how hard I try to understand, I just can't get the concepts. On top of that I am probably the worst writer in my class. My sentence structures and range of vocabulary are a joke compared to everyone else in the class. I really want to drop this class, but it would be so embarrassing; its also my only AP class, so if I fail it or drop it, it would probably look terrible on my transcript.
I'm so tired of being extremely frustrated over this class and feeling like a complete idiot. All I want is to get into a good college.

How can I get better at English?
