Concerns About Tonight's Test

So there's a test tonight. I'm semi-prepared. Meaning I read over the "Almost 100 Things To Know About Computers" exactly one time. In actuality there's only 78 items on the sheet. I'm not sure if I would consider that "almost 100". Let's just say if I got a 78% out of 100 on this test, I wouldn't shrug it off and try to convince myself that it's almost 100.
