# Exam Information for Math 125

## Fall 2009

As it says on the course syllabus, there are two midterms and a final in MAT125, which count for 25%, 25%, and 35% of your grade, respectively. No Make-up exams will be given. If you miss an exam due to a documented medical or family reason, that score will be replaced by the grade on the balance of the course. If you miss more than one exam for such reasons, you should probably withdraw from the course.

### First Midterm: 8:30 pm on Tuesday, October 13, 2009

Bring a photo ID. No calculators will be allowed. Bring a pen to the exam: while you may do the midterm in pencil (or crayon), you can only contest grading of problems done in non-erasable ink. Sorry.

The midterm covers sections 1.1 through 1.6, Appendix A, B, C, and sections 2.1 through 3.1 of the text.
Doing all of the homework problems (including the first 10 problems of HW 06, which isn't due until after the exam) prior to the exam is a very good idea. Doing additional problems from the text can be helpful.

You should be able to do all the problems on these practice exams from previous semesters. However, keep in mind that our exam is later in the semester than in some previous years, so most of these don't cover derivatives. Ours will certainly include some derivative problems.

Results: While there were a couple of tricky problems on the exam, the majority of the problems were quite standard, and similar both to the homework and the sample exams. Nevertheless, many people did terribly. Below is a graph of the score distribution on the exam.

 low score: 2 mean: 41.8 median: 44 high score: 74 possible score: 74
range letter grade
62-74 A-, A
45-64 B-, B, B+
30-44 C, C+
25-29 C-
15-24 D, D+
0-14 F

You can check your grade here. If you got less than 30 on the exam, you should seriously consider moving down to MAT123, which can be done with this form.

There were three different versions of the exam. Here is Version A (Solutions), Version B (Solutions), or maybe Version C (Solutions) is your pleasure. They are pretty similar, though.

### Second Midterm: 8:30 pm on Monday, November 16, 2009

The second midterm will cover the material we have covered since the first exam: sections 3.1 through 4.1.
PLEASE BRING A PEN, as well as a photo ID.

Here are some sample problems (solutions) you can work on to help yourself prepare, as well as the midterm from Fall 2008 (solutions).

Results: A lot of people did quite well on this exam, but many did awful. Two people had no points taken off.
Below is a graph of the score distribution on the exam.

 low score: 1 mean: 51.2 median: 54 high score: 85 possible score: 85
range letter grade
75-85 A-, A
55-74 B-, B, B+
35-54 C, C+
30-34 C-
10-29 D, D+
0-9 F

You can check your grade here. If you got less than about 35 points on the exam, you will need to make some significant changes if you expect to pass the course.

If you want to relive the magic, you can grab a copy of the midterm and go wild. There were two very similar versions: midterm Version 1 (solutions), and midterm Version 2 (solutions).

### Final Exam: 8 am on Monday, December 14, 2008

The final will be cumulative, covering everything that we have done in the class. However, extra emphasis will be on material since the second midterm. It is much more important that you understand how to do calculus than memorize a bunch of formulae. So, I will let you bring a single sheet of notes with you to the exam. This note sheet must be handwritten, not a xerox or a printout. It can be written only on one side of the page, the page can be no larger than a standard sheet of letter paper (8.5" by 11"), and the sheet must be turned in along with your exam. Students using notes which don't fit this guideline will be charged with academic dishonesty. Note that you can write whatever you think will be helpful on your notes: formulae, examples, or the lyrics to your favorite song.

In order to study, you should do lots of problems. While doing the Extra Credit assignment on WebAssign will help, it isn't sufficient unless you are already well-prepared. Remember that you can also get the solutions to all the old online homeworks in WebAssign.

In addition, here are some practice problems from Fall '06 (solutions), spring '06 (solutions), and some review problems I wrote in 2004 (solutions). Please work the problems before reading the solutions, or they won't do you any good.

Results: The final had a few difficult problems, but also some easy ones. As usual, some people did well, others did terribly.
Below is a graph of the score distribution on the exam.
