Hey man,
I'm doing it too. The tips I could was to know a lot of verb tenses as they award the variety of tenses used. Also, know as much vocabulary as you can so that you won't miss words in the middle of the essay. Do this and you get an easy A. I know that what I said was like what all people telll you but it is just the best trick.
By the way, how was your listening? I found it like really easy. I'mma get an A I think.
