You are welcome to stop by any of my office hours next quarter to see your final exam. If you agree with the grading, you can take the final with you; once the exam has left my office, no scores changes can take place.
Course grades have now been calculated and are available on Catalyst. These are the actual course grades, with the course curve. Lowest homework scores were dropped in the calculation of your homework average, but all homework scores appear as a matter of record. You are welcome to stop by my office hours once Spring quarter starts if you would like to see your final exam.
Some of you received 1 point of extra credit on your final exam. This is shown in the Extra Credit column on Catalyst. If this column is blank, it means that you did not receive any extra credit.
Here are the final exam statistics: n=289; min=1; 1st quartile=29; median=42; 3rd quartile=56; max=80 (3 students)
Course grade are now being calculated.
Grading of finals is taking longer than usual. I won't have an office hour before Spring quarter. If you would like to see your final exam, you are welcome to stop by during any of my office hours during Spring quarter. Scores and course grades should be available on Catalyst in the next couple of days.
Have a good break!
I have made my decisions on the extra credit "underground ferris wheel" question. I considered the following ferris wheels to be winning entries, and those who submitted them first will get a bonus point on their final exams:
Though the review sheet posted below does not make it clear, linear-to-linear rational functions are not a topic you need to concern yourself with for the final exam.
There will be a Math 120 review at CLUE, 6:00 to 8:00 pm on Friday, 9 March in MGH 251.
Here is a review sheet for the final exam.
Answers to the second midterm exam are now on the exam archive at the 120 Materials Website (link at right).
You now have access to your scores in the Catalyst Gradebook for this course. This is available via your MyUW. Please check that your scores have been recorded correctly. If you find an error, please bring your graded work to your TA so they can verify the error and make any necessary changes. The gradebook also has an estimate grade. This is an estimated course grade, since it does not include the final exam or the last homework assignment. Your lowest homework score was dropped during the calculation of your estimated course grade, but it still appears in the gradebook as a matter of record. An estimated course grade of 0 indicates that your performance was not of sufficient quality to qualify you for a grade of 0.7 or higher.
The final exam makes up 35% of your grade, so a good final exam score can increase your course grade quite a lot, certainly 0.5 is possible, especially if your grade now is low, and even greater increases have been seen.
Statistics on the second midterm exam: n=291; min=2; 1st quartile=15; median=18; 3rd quartile=22.50; max=40 (one student).
The circular motion examples link at right (under Handouts and Supplements) has a template for solving the circular motion problems you'll see in chapter 17. The first example is the one from today's lecture, but there is a second one.
Here is a review sheet for the second midterm exam.
Here is a list of problems in the exam archive which are relevant to the second midterm.

Answers to the first midterm exam are now in the Math 120 exam archive on the Math 120 Materials Website (link at right).
Statistics for the first midterm exam: n=309; min=4; 1st quartile=21; median=27; 3rd quartile=32; max=40 (6 students).
Here is table giving an approximate 4.0-scale interpretation of your exam score. This is just to give you a rough idea of how you are doing. The curve used to create this interpretation will not be the same curve used at the end of the course to determine your grade, since that curve will involve more data, but it will be somewhat similar.

The homework schedule has been updated once again. As a result of the missed classes due to snow, I have removed chapter 14 from the course this quarter. This chapter covered linear-to-linear rational functions. When studying for the second midterm exam and final, you should skip problems in the exam archive involving these functions.
Here is a review sheet for the first midterm exam. The exam will cover chapters 1-5 of the text.
Usually the test archive (available via the Math 120 Materials Website (link at right)) is a good resource for preparing for the midterm exams. However, due to the snow cancellations, the first midterm this quarter will cover less than those exams cover. The following are the only problems on the last bunch of Midterm 1's that you should use for practice; other problems involve topics in later chapters. Unless otherwise noted, all exams are from my previous classes (i.e., the link will say Conroy).
| quarter | problems to consider |
| 2011 Autumn | 1, 2 |
| 2011 Spring | 1, 3 |
| 2011 Winter | 1, 3, 4(a) |
| 2010 Autumn B | 1, 2 |
| 2010 Autumn C | 1,2 |
| 2010 Winter | 1,2, 4(b) |
| 2009 Autumn (Conroy) | 2, 3, 4 |
| 2009 Autumn (Loveless) | 1,2 |
| 2009 Spring | 1,2 |
| 2009 Winter | 3,4 |
| 2008 Autumn (Conroy) | 2,3,4 |
| 2008 Autumn (Loveless) | 3(a),4 |
| 2008 Spring | 1 |
| 2008 Winter | 2 |
Keep in mind when studying for the exam that you will have 50 minutes to work four problems. As you practice with these old exams, try to assess whether or not you are working quickly enough to get four problems done in 50 minutes.
Welcome to Math 120 A, B Winter quarter 2012.
Announcements and other useful things will be posted here during the quarter, so check this site frequently.
Textbook: The textbook for this course is Precalculus, by Collingwood, Prince and Conroy. We will use the 2011-12 edition (this is the latest edition). The book can be purchased at Professional Copy and Print, located at 4200 University Way (on the Ave one block south of the UW bookstore). It is not available at the UW bookstore.
You do not have to purchase the textbook. It is available electronically on the Math 120 Materials Website (link at right).
Discussion Board: The course has a discussion board (link at right). This is a great way to ask questions of me in a way that will benefit all students in the course. You can ask about homework questions, studying methods, etc. You can also use it to coordinate study sessions with other students.
Homework Schedule: The homework schedule is available at right. This is the only place this information is available, so please check here to get the schedule.
