Old exam problems - relevant problems from last fall's course, all lumped together. As exam time approaches I'll post a list of the old exam problems that are most relevant to the upcoming exam, plus some hints.
Old exam solutions - sorry, but I won't post these - they are of no use as study aids (trust me, it's for your own good). I would be happy to go through old exam problems with you, and I will be happy to give you feedback on your solutions to these, but I'm not going to post solutions. Notice the similarity between most exam problems and HW problems. Notice also that for most exam problems, there are about 5 similar HW problems with solutions!
Current semester exam answer keys: Final Exam
Final exam scores, HOQ points, and course grades by ID number (with permission). (A signed permission form, approved by the Registrar's Office, is on file for each student specifically authorizing the posting of grades in this manner.) Look for this link to become active around July 13ish.

HW sets, answer keys, and lecture notes are available above as .pdf files. You'll need Adobe Acrobat Reader. (You can download it free of charge). If you can't get either the display or the printing to work, use a computer in the CRC or one of the OIT computer labs on campus.

Homework corrections and clarifications -

If you find something in the HW sets or solutions that you think is incorrect, don't hesitate to let me know. Same thing goes for exams - you can always ask if something is a typo. (There's nothing worse than having a huge number of students waste time struggling with an exam problem that's impossible because there's one H or a charge missing from the formula - so say something.)

Stats for the most recent exam -

Final exam -

Average = 146 (58.6%)

Range = 45 - 213

Approximate letter grade ranges for this exam - i.e. this would be your approximate course grade based only on this exam, assuming you earn the maximum number of quiz points by the end of the semester.

A: about 200 and up

B: about 160 - 199

C: about 120 - 159

D: about 85 - 119

I'm not going to set + and - borderlines - if you're in about the high third of the B range that's a B+, if you're in about the lower third in the C range, that's a C-.
