My GRE exam is on 20th August, still I am not confident about awa and facing hard times how to improve it. here i have attached 2 essays from my power prep 1 test. It would be so helpful if someone could give me valuable suggestion about how to focus on the topic, improve writing by adding some skills and what points I am missing in the writings. Also If I write essays like this level what score in AWA I am supposed to get? Any help will be greatly appreciated.
