How to get a 4 or 5 on AP 2-D Art portfolio?

Hello!
I’m currently taking AP 2-D art. I really like the class and would like to get a good score. I’m a decent artist, I guess.
However, my Ap art teacher is pretty bad. She does not teach whatsoever and offers terrible art advice. Any time I go up to her and ask about my art, she doesn’t give any constructive criticism and starts talking about random topics like food (just never art).
So, what does your art teacher teach you about art submissions? Mine only tells me to make ‘good art’…How do you add the ‘design’ aspect into your art? I don’t know how to word this question… I guess what qualifies as ‘design’? I’m guessing that drawing people all the time doesn’t qualify as design because that’s more of an AP drawing thing. Sorry, I’m totally clueless about this class…
Thanks!
