So, I finished final number three of four, and there's a sketchy story. A little background first: the guy who taught the class last year (L) posted pretty comprehensive notes online because he's planning on writing a book or something. My professor(who is not L) is really lazy and has been teaching the class from L's online notes. So Will was poking around L's website and found the documents from L's class last year (not that they were hidden or anything: there just wasn't a link on the main page). This included a copy of the final exam from last year, complete with solutions. So when I got up this morning, I went through the final and worked out most of the problems, figuring it would be good practice for my final. And it was in fact damn good practice. One problem on the final I just took was exactly the same as one from L's final and another two problems were damn close (this is out of seven problems). Now, I know this is my professor's fault. He should have written his own damn test. But I still feel kind of sketchy about the whole thing.
