Panic mode

I have until May 1st to write my midterm. I still have about a chapter and a half to go through. What are the chances that I can write it tonight? If I don't, the only other times I can write it are Monday night, maybe Tuesday night (but unlikely), and Wednesday night. I'd rather not leave it until Wednesday, but I might not have a choice. ARGGHH! [mental note: don't sign up for another course without evaluating what your workload is like at work]
