Here are the solutions to today's midterm. Note that there were multiple versions, so your actual answers might be different from these. (Sorry about the missing 'A's in the PDF. Apple's iOS 9 update appears to have broken its PDF compiler.)

October 21: Hey, there's a midterm next week! Some things you should do to study:
    • See this list of topics.
    • Practice old exams here.
    • See this forum post for a list of old exam problems sorted by chapter.
    • Practice the DFEPs.
    • Go to review sessions. I'm holding one on Monday (Oct. 26th) afternoon, from 3 PM to 5 PM in Bagley 154 (our usual classroom). CLUE is holding another review session on Monday evening, and you should get an email soon with some details.

    Assignment #3 (due 10/13)
    Assignment #4 (due 10/13)
