An impossible exam

I am accessing the Internet in my home now after a couple months I could not do that.
I have the mid-term exam of the American history. There are 57 potential identification terms and 9 essay questions from our professor that I have to study within the weekend. I just don’t have enough time to prepare them well. The only thing I can do is to try my best, and then I will never blame myself even though I may receive a C on the exam.
