I’ve uploaded a corrected version of the solutions to the Math 421 UDrive.

**In case you lost credit on #9 (b) because of my error, please bring your paper with you to the exam Tuesday and I’ll fix it.**

(If I marked that problem as correct because of my mistake, you need *not *show me your paper to get any credit deducted!)

Monday 13 December 2:00–4:00 p.m., my LGRT 1335G office.

You may pick up your graded Homework 9, or any previously uncollected exam or homework paper.

Complete solutions have been uploaded to the usual UDrive location.

There were some too-common errors made in Homework 9 solutions, especially some conceptual errors. Please see this list of common errors there.

- Reminder that the Final Exam Tuesday (at 8:00 a.m.) is in our usual classroom, LGRT 219
- I’ve posted a list of the additional Final Exam topics—the ones since Exam 2. Lists of topics from Exams 1 and 2 are there, too.

**Tuesday, 14 December
8:00–10:00 a.m.

In case of a final exam conflict, you must provide me with written documentation from the Registrar’s Office no later than Tuesday, 1 December.

You have a final exam conflict only if there is another officially-scheduled final exam at the same time.

To see which in which course you are entitled to a final exam make-up, look at **the last digit of the 5-digit class number** of the other course and of Math 421. Our class number is 73992. You are entitled to a make-up for the exam in the course where that digit is higher. Thus if the other course has the last digit of the 5-digit class number 3 or higher, then you get a make-up for the final there. If the last digit of the other course’s class number is 2, the same as ours, then look at the next-to-last digit, etc.

Such documentation, signed by a representative of the Registrar, should include:

- The course whose final exam conflicts and the 5-digit class number for that course
- Contact information for the instructor of that conflicting course
- A copy of your entire final exam schedule
- Your contact information: UMass e-mail address and telephone number
