announcements
  • i hope to do up final exam solutions but it may not happen until next week
  • final exam statistics: mean 41.7/60, median 47/70, high 63/70
  • office hours before the final: thursday may 11 2:00-4:00 pm, and by appointment
  • some practice problems (v2) for the final exam (including problems on material covered in the last week). final exams from previous years are here, here, and here. as with the midterm, note that the topics in the course vary from year to year; of course i'll only test you on material we've covered in class.
  • the final exam will be in hodson 216 from 9-noon on friday, may 12. everything from the course is fair game, but there will be a decided emphasis on material we've covered since the midterm.
  • midterm statistics: mean 19/40, median 16/40, high 30/40
  • midterm solutions
  • some midterms from previous years are here, here, and here. note that some topics appeared in these which won't be on our midterm (e.g. group theory), whereas some topics which will definitely be on our midterm did not appear in these (e.g. modules over a pid).
  • the first midterm will cover sections 5.1, 5.2, 6.1, 7.1, and 7.2 (but nothing else in chapter 6).
  • the course will begin with section 5.1 in the text. knowledge of the definitions and statements (but not the proofs) of everything in sections 4.1-4.3 will be assumed in this course (i will also intersperse reminders about this material as we develop new material). i will not assume anything from sections 4.4-4.6.

    course content
    the rough plan for the course is to cover some subset of chapters 5-7 and 9-11 in nicholson, with the precise choice and order of topics to be made on the fly. we will begin at the start of chapter 5. the departmental syllabus for this course is here; we will surely deviate from it in places.

    homework
    homework will be assigned throughout the week and due the following monday. please staple your assignments. late assignments will not be accepted, unless you have obtained written confirmation (over email) of an extension from me in advance. you are strongly encouraged to collaborate with each other on homework, but your assignments must be written up independently and in your own words. copying is strictly forbidden.

    midterm
    there will be an in-class midterm on wednesday, march 15.

    if you have to miss the midterm for a documented, legitimate excuse, then the corresponding component of your final grade will be calculated by prorating your final exam score. in case of sickness, a doctor's note must be obtained on or promptly after the exam date. there will be no make-up exams.

    final exam
    friday, may 12, 9-noon

    grading scheme
    40% homework, 20% midterm, 40% final exam
