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 Makeup 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.

The first midterm was at 8:30 pm on
Monday, September 27. Bring a photo ID. No calculators.
The midterm covers sections 1.1 through 1.6, Appendix C, and sections
2.1 through 2.4 of the text.
Doing all of the relevant homework problems,
as well as other problems from the text,
prior to the exam is a very good idea.
You should be able to do all the problems on these practice exams
from previous semesters:
practice1,
practice2.
Also, here is an
exam from a few years ago.
The solutions are also available, but please work the problems out first
before looking at them, or you won't learn anything. Here are the
solutions to practice1,
solutions to practice2, and
solutions to the old exam.
The questions on the exam cover the same topics but will, of course, be
different.
Results: The class as a whole did much worse than
anticipated on this exam. Part of this may have been due to a lot of people
not taking seriously the suggestion of doing all the homework before
the exam. Only about 25% of you submitted any work on HW3 it iLrn
before the exam. There is a very strong correlation between the scores on
the homework, which you can see by this graph.
Below is a graph of the score distribution on the exam. The grades given
were very generous, probably too generous.

mean: 45 
median: 46.5

Just in case you lost yours, here is the exam,
and here are the solutions.

The second midterm was at 8:30 pm on
Tuesday, November 9.
The midterm covers sections 2.5 through the end of chapter 3 in the text.
Doing all of the relevant homework problems,
as well as other problems from the text, prior to the exam is a very good
idea.
Here is an exam I gave in 1999, to give you some
idea of what to expect. Here are
the solutions, but please
do the problems before looking at the solutions.
Note that we have covered more
material; in particular, that exam only covered through the chain rule.
You are also responsible for the rest of the material in chapter 3,
including the derivatives of the six trigonometric functions, inverse
trigonometric functions, the logarithm, and implicit differentiation.
Here are some more problems you can use to help
you review. Here are
the solutions, but again, don't look at them
until you have fully worked out each problem or you won't learn anything.
Really.
Results: As you can see from the grade distribution below, there are
two distinct populations of students: a large group who mostly seems to be
getting it (about 60% of the class), and another large group that is having
a lot of trouble. If you are in the group in trouble (that is, you got less
than 50 on the exam), you need to take steps to improve your understanding,
or you will not pass the class. Your TAs and lecturers are willing
to help, but clearly you are not approaching the class material effectively.
low score: 0 
mean: 55.1 
median: 56.5 
high score: 100

For your enjoyment, here is one version of
the exam, and a set of
solutions to it.
Also, here is the other one, and the
solutions for that one.

The final exam will be at 11 am on
Wednesday, December 15. The specific locations are listed below.
For the final, you may bring with you an index card with whatever you want
written on it, provided that the card is entirely handwritten (no
photocopies or printouts allowed), that
your name is written legibly on the card,
the card is no larger than 8.5" by 5.5",
and that you turn the card in along with your exam.
Students using notes that don't meet these specifications will have the
notes and the exam confiscated and will be charged with academic dishonesty.
Note that the "index card" can be half a sheet of ordinary paper.
No calculators will be allowed.

Here are some review problems, and
solutions to most of them. Also, here is
a copy of the final I gave in 1999. Keep in
mind that the presence of multiple choice problems on that exam doesn't
imply there will be multiple choice on this year's model.
Solutions will show up here around Dec 12 or 13.
Note also that the first two exams, as well as solutions, are posted above
on this page. Solutions to most of the homework sets are on the homework page.
There will be a review session on Monday, Dec 13, from 57:30pm in
Heavy Engineering 201. There will be a second session Tuesday, Dec
12 from 12pm in Math P131.
