I am an idiot...

I am taking an online course called Tests and Measurement. It is basically a statistics course. My first exam is Jan 30, and it will be up from 12:00 midnight to 11:59 PM. I have been studying and getting psyched to knock this thing out at midnight. I just realized that these times are based on Central time. I don't see me staying up that late to take a statistics test, so I guess I will be doing it in the morning. If I can't figure out when the test starts, how does that bode for my prospects on this exam?
