I CAN'T WRITE TO SAVE MY LIFE

I'm taking AP Lang this year, even though I'm the last person who should be because for the life of me, I cannot write literary analysis essays, and I know that AP Lang focuses on rhetorical analysis BUT all my friends who took the class previously say that you have to be able to identify the same things you would in literary analysis (theme, figurative language, chracterization, etc.) and write about them. I NEED ADVICE on what I can do one month before school starts so I don't actually fail the class.
