Exam I solution / Friday's quiz

Exam I and its detailed solution can be found here.

As mentioned today in class, rescaling was accomplished by dropping question #2, and regarding it as bonus. Basically, all you have to do is take the total number you got correct, including the bonus, and divide it by 24 instead of 25 to get your percentage. After that, the usual >90=A, 80-90=B scale applies.

On another note: this Friday's quiz (5 Oct 2007) will consist entirely of questions from the exam, verbatim. Most likely, some of the questions you solved in class today will be chosen.

So. Work through the solutions ... and this week's quiz will be a 'gimmie.'
