Final exam grades have been posted on MyUCDavis. Letter grade ranges are posted below. If you want to look over your exam, come to my office, MSB 3218, 1:00-4:00 Wednesday, 12/12.

Rob Gysel has arranged a review session on Sunday, 7:00-9:00 PM, in Kleiber 3.

The final exam will be in Chem 194, 10:30-12:30 on Monday, December 10. Be sure to bring your ID card.

A practice exam and solutions have been posted below.

**Please note**: if you need any special arrangements for the
final exam (if you are taking more than one Math 21, or if you have
a disability and need extra time), you must email me *immediately*,
as I am required to make arrangements by Wednesday, 12/5.

Grade ranges for exam 2 have now been posted below.

There will be a question-and-answer session the evening before the second exam, Tuesday November 13, 7-8 PM in 198 Young.

The final weekly homework is the homework assigned on 10/26, with corresponding quiz on 11/1. Starting Monday, 10/29, homework will be posted after every lecture. It will still be grouped on the web page into "assignments" corresponding the quiz material for each week's section. There will be one assignment covering 10/29, 10/31, 11/2, and 11/5. Subsequent assignments will cover from Wednesday through Monday, and be quizzed on Thursday, 3 days after the last part has been assigned. This way, you will be able to start on your homework further in advance, but the timing of section material, homework material, and lecture material will match better.

Pick up your exams in Rob's office, 3129 MSB, on Tuesday, between 3:30 and 5:30 (try other times on Tuesday if you cannot make this one). Don't forget the drop deadline is Wednesday, 10/24.

I will not have my usual Friday office hours this week, October 19, as I will be out of town for a conference. Rob Gysel has agreed to hold extra office hours on this day, from 1:00-2:30, in his office, MSB 3129.

Discussion sections will *not* be meeting on
Thursday, September 27. They will begin the following week, after the
first lectures.

A more detailed syllabus may be found here.

**The first exam** will be given on Friday, October 19, and will
cover the material of Chapter 2. It will be graded prior to the drop
deadline, which is October 24.

these are not complete solutions; you will be expected to show full work.
They are only intended to allow you to check your answers)

**The second exam** will be given on Wednesday, November 14, and will
cover the material of Chapter 3, except sections 3.9 and 3.10.

Practice Exam 2

**The final exam** is scheduled for Monday, December 10, 10:30-12:30,
in Chem 194. It will cover material for the entire course, but will
emphasize chapter 4.

Practice Exam 3 has been posted. It is
a practice hourlong exam covering the material since the last exam, to
help you prepare for the final.

The first exam's grades are now visible on MyUCDavis. The mean score was
38%, median 35%, and standard deviation 18%. The letter grade ranges are
as follows:

55%-100%: A range

40-54%: B range

20-39%: C range

10-19%: D range

0-9%: F

Partly because many people received negative scores on the true/false section, the second exam will be weighted more heavily for people who do better on it. Specifically, the scores will be converted to letter grades, and then anyone who does better on the second exam will have the exams weighted as 10%/30% rather than 20%/20%.

The second exam's grades are now visible on MyUCDavis. The median score
was 82%. The letter grade ranges are as follows:

75%-100%: A range

55-74%: B range

35-54%: C range

25-34%: D range

0-24%: F

The final exam's grades are now visible on MyUCDavis. Note that the
exam was out of 200 points, and what follows is in terms of percentages,
so divide the raw scores by 2.
The median and mean scores were 58%. The letter grade ranges are as
follows:

70%-100%: A range

55-69%: B range

35-54%: C range

25-34%: D range

0-24%: F

Grading will be on a soft curve, meaning that I do not predetermine either what scores correspond to what grades, or what percentage of students get what grades. Rather, after grading each exam I will assign grade ranges using the following general criterion: those who earn an A should demonstrate a strong mastery of nearly all the material; a B should correspond to a good working knowledge of a strong majority of the material; and C should correspond to an ability to solve routine problems in a majority of the topics covered.

For your convenience, the homework problems available in MyMathLab will also be posted there as homework assignments. However, you should be sure to check the full assignments above for problems not offered in MyMathLab. Unfortunately, MyMathLab does not allow homeworks to be posted incrementally. I will therefore have to make a new assignment each time I add exercises after lecture. These will be labelled something like Homework 4, Homework 4b, Homework 4c. Don't bother redoing problems you have already solved in an earlier version.
