This course makes use of the web-based Quest content delivery and homework server system maintained by the College of Natural Sciences. This homework service will require a $25 charge per student per class for its use, with no student being charged more than $50 a semester. This goes toward the maintenance and operation of the resource. Please go to http://quest.cns.utexas.edu to log in to the Quest system for this class. After the 12th day of class, when you log into Quest you will be asked to pay via credit card on a secure payment site. Quest provides mandatory instructional material for this course, just as is your textbook, etc. For payment questions, email quest.billing@cns.utexas.edu.

Grading Scheme
During most lectures I will give short multiple-choice quizzes, which will count 15% towards the course grade. They cover topics from the current and previous lectures. For the quizzes you will need to own and register an iClicker and to enroll in this course. Read about Quest here.
At every lecture I shall assign homework, which is to be turned in on the Thursday of the following week. I will not accept late homework, but I will drop the three lowest or missed homeworks. The homework counts 15% towards the course grade. You are encouraged to collaborate in groups on the homework and further study, and to turn in only one homework per group. The groups can be arbitrarily large; in fact, I will not accept homework with fewer than two names on it.
There will be three (3) midterm tests, each worth 15% and covering the material presented prior to the test.
The comprehensive final test counts 25%. The worst (or missed) midterm test is replaced by the score from the final test if that improves the total. I can't allow you to miss two or more of the midterm tests, though, and there will be NO (0) make-up test.
I do not like to grade on the curve, so the grading scheme is this:
90-100: A, 80-89.9: B, 70-79.9: C, 60-69.9: D.
However, since most students prefer to be graded on the curve I will modify this scheme a little: I'll give grades A-, B-, C-,D- at cutoff points lower than 90, 80, 70, 60, respectively, so as to approximate a curve.

Regrades and Disputes: I grade very leniently. If I make a mistake in grading please let me know and I'll fix it--provided the request to change a score is made within one week of the test or homework in dispute being returned to the class. However, the way I apportion partial credit is my prerogative and I will not change it. I will not entertain arguments about it; they merely generate ill will.
Just in case disputes over your record should arise keep all tests, homeworks, quizzes etc.
I am not permitted to change this grading scheme, for example by assigning extra work if a few points are missing for a higher grade. Also, I do not cook the books, not even for the most charming, needy, or pushy student.

The midterm tests are scheduled on the following Thursdays during class time: February 20, March 27, and May 1. The final test is scheduled for Monday May 12 at 2:00 PM in NOA 1.102. Put these dates on your calendar now!
Most test problems are taken from the book, perhaps slightly altered. There are usually 5-6 problems per test, 7-10 for the final test. The test questions are taken from the book, possibly slightly modified to make them easier.

How to learn: The most efficient way to learn the material is to collaborate and to read ahead. I will post slides covering the next one or two lectures on the web. They can serve as your notes, so you won't have to scribble along. You save a lot of time by reading them in advance, so you can ask questions during the lecture. Also, think how much easier it is to answer a quiz if you have thought about it beforehand.
