Exam Information for Math 132

Spring 2013

As it says on the course syllabus, there are two midterms and a final in MAT132, 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: 8:45 pm on Monday, March 4, 2013

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.

Locations: The exam will be in various locations around the campus. Where you should go depends on which recitation you are enrolled in. The specific locations are below.

Lecture 1 (R01, R02, R03, R05) ESS001
Lecture 2&3 (R06, R07, R09, R10, R11) Harriman 137

Material: The midterm covers sections 5.5, 5.6, 5.7, 5.9, 5.10 and 6.1 of the text (sections 5.1-5.4 were review and won't be explicitly covered, but knowledge of the material is relevant).
Doing all of the homework problems prior to the exam is a very good idea. Doing additional problems from the text can be helpful.

It is important that you know the basic collection of integrals (which correspond to the derivatives of the standard functions), standard trig identities, etc. A list of these appears on page 358 of your text and inside the front cover (or see here).

Except as noted, you should be able to do all the problems on these practice (and actual) exams from previous semesters. Of course, ability to do all of these is not a guarantee of success on the midterm; the actual exam will cover similar material, not identical problems.

Results: In general, people did well on this exam. There were a lot more grades of A than usual; it is unlikely there will be as many A grades on the next midterm.
But there were also quite a few poor grades. If you received a grade of less than 90 on this midterm, you are in danger of needing to retake the course. If you expect to get a grade of C or higher, you will need to change how you approach this class. If you are irrecoverably lost, you might want to consider moving to MAT126 or MAT131 instead; this can be done by filing this form with the registrar before 4pm on Friday, March 8.

Below is a graph of the score distribution on the exam.

There were three different versions of the exam. They are the electric version (Solutions), the acoustic verion (Solutions), and the instrumental version (Solutions). Collect 'em all!

Second Midterm: 8:45 pm on Wednesday, April 10, 2013

PLEASE BRING A PEN, as well as a photo ID. While you may do the midterm in pencil (or crayon), you can only contest grading of problems done in non-erasable ink.

Locations: Below are the locations of the rooms for the exam. Note that you will not necessarily be in the same room you were in for the first exam.

Lecture 1 (R01, R02, R03, R05) ESS001
Lecture 2&3 (R06, R07, R09, R10, R11) Old Engineering 143

Material: The second midterm will cover the material we have covered since the first exam. That is, volumes, arc length, average value, work, (skip pressure, centroids, center of mass), polar coordinates (graphs and area), sequences, and infinite sums (including power series). These topics are covered in the textbook in sections 6.2 through 6.6, appendix H, and sections 8.1 through 8.5.

Keep in mind that ability to do these problems is no guarantee of success on the midterm; the actual exam will cover similar material, not identical problems.
Note also that in several previous semesters, the timing of the second exam and the order in which they did the material differed, so some of the material may vary.

Please attempt to do the problems in the sample exams before looking at the solutions. You will certainly learn more that way.

Results: Below is a graph of the score distribution on the exam.

low score: 1(2) mean: 45.5 median: 47 high score: 75(3) possible score: 75
range letter grade
62-75 A-, A
45-61 B-, B, B+
35-44 C, C+
30-34 C-
20-29 D, D+
0-19 F

As you can see from the distribution, quite a few people did well, but sadly there were also quite a few people who did very poorly. There were three people who had no points taken off, but also two people who only earned one point on the entire midterm.

Exam: You can get a copy of the exam, and also the solutions. Only a limited number of these valuable collector's editions will be printed, so they are sure to increase in value. They are available in two delicious flavors: papaya (solutions) and guava (solutions). Order now! Operators are standing by.

Final Exam: 8:00am on Monday, May 20, 2013

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.

The final will be in Javits 100 for all students.

Please bring a photo ID to the final.

The final will have two parts.

Practice exams: Here are some practice problems from previous years. Note that the selection of topics covered is not exhaustive: there are probably topics we have covered that may be on the final which are not covered in these exams. Please work the problems before reading the solutions, or they won't do you any good.

Review/Problem Sessions

Results: The performance on the final was, overall, pretty disappointing. But finals are a stressful time, so I guess your brains were not firing on all cylinders. There was only one person who got at least 70 points on part one and didn't also get enough points on part 2 for a C. There were lots of flying pigs after all! Also, it seems that a large fraction of the class can't has reading after all (image courtesy Louise Deon, Fall 2011).

Below is a graph of the score distribution on the exam. This is based on the combination of parts 1 and 2.

Part I low score: 1 mean: 68 median: 70 high score: 100 possible score: 100
Overall low score: 1 mean: 123 median: 128 high score: 215 possible score: 215
range letter grade
185-215 A-, A
130-184 B-, B, B+
100-129 C, C+
80-99 C-
40-79 D, D+
0-39 F

Course Grade Overall

Based on the final, you'd think that there were more low grades, but overall, a lot of people did OK.

The homework grades were pretty high overall, see the graph below. As you can see, a lot of people took advantage of the extra credit; more than 28% of the class had better than 100% on the homework part of the grade. Keep in mind, however, that homework is only worth 15% of the total grade.

And here is the distribution of grades given. Half of the class got a grade of B- or better. The number of A and A- grades was about usual for this class, but there were quite a few more C grades than expected.
If you got a C-, don't ask me to change it to a C unless one of your grades is recorded wrong. I looked carefully at all of the C- grades, and no one got a C- who I didn't think needed to retake the class.
