Course grades are now posted on Catalyst. These are the actual grades I will be sending to the registrar, so they include the course curve, and the dropping of your lowest homework score. The dropping of the lowest homework score was performed during the calculation of the grade; all scores appear in the gradebook as a matter of record.
Have a good summer!
Here are the final exam stats: n = 125; min = 3; 1st quartile = 30; median = 45; 3rd quartile = 56; max = 70 (1 student)
Course grades have not been calculated yet. Catalyst will be updated as soon as they are done.
Graded final exams will be viewable during an office hour on Friday, June 10, 1-2 PM. Scores will be added to Catalyst today or tomorrow. Final exam can also be seen any time during Autumn quarter.
CLUE will hold a Math 120 review on Friday, June 3, at 7 PM in Mary Gates Hall room 241.
Here is a review sheet for the final exam.
Statistics on the second midterm exam:
n=126; min=6;
1st quartile=20.25; median=26; 3rd quartile=32; max=39.
Estimated current grades will be posted to Catalyst later this week, so a 4.0 conversion table for this exam will not be posted.
Answers to the second midterm are now available at the test archive on the 120 Materials Website (link at right).
Problems suggested from the exam archive have been updated. Please see below.
CLUE will be holding a 120 review session on May 18 at 7 PM in Mary Gates Hall.
For more examples of uniform circular motion, check out this (also linked at right).
UPDATE: The suggested problems have been updated to reflect the postponement of circular motion problems, and to remove quadratic optimization problems (which were covered on the first midterm exam).
When using the exam archive, you need to be aware that not all problems on all second midterms are relevant. Here are some suggestions of good problems to use for practice.
PLEASE NOTE: Some of the problems below may involve uniform circular motion (e.g., motion around a track). Such problems will not be on the second midterm.
Here is a review sheet for the second midterm exam.
An example of how to handle the most extreme linear to linear rational function case (i.e., when three points are given, so no asymptote is immediately known), is available under Handouts and Supplements (at right).
I've added an applet under Handouts and Supplements (at right) illustrating how the paremeters of linear to linear rational function effect the graph.
Answers to the first midterm are now available at the 120 Materials Website (link at right).
The following is a table to help you interpret your exam score. This is entirely approximate: I make no use of these grade equivalents: it is just for you to get an idea of how you did, on a 4 point scale.
| exam score | APPROXIMATE grade equivalent |
| <17 | 0.0 | 17 | 0.7 | 18 | 0.9 | 19 | 1.2 | 20 | 1.4 | 21 | 1.7 | 22 | 1.9 | 23 | 2.2 | 24 | 2.4 | 25 | 2.7 | 26 | 2.8 | 27 | 2.9 | 28 | 3.0 | 29 | 3.1 | 30 | 3.2 | 31 | 3.3 | 32 | 3.4 | 33 | 3.5 | 34 | 3.6 | 35 | 3.7 | 36 | 3.8 | 37 | 3.9 | 38 | 4.0 | 39 | 4.0 | 40 | 4.0 |
Statistics for the first midterm exam: n=137; min=9; 1at quartile=18; median=25; 3rd quartile=31; max=40 (3 students)
CLUE will be holding a Math 120 review on Wednesday, April 20, at 7 PM. It will be in Mary Gates Hall.
Here is a review sheet for the first midterm exam.
The exam archive is available via the 120 Materials Website (link at right).
Welcome to Math 120 A Spring quarter 2011.
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 and Prince, the 2010-11 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. The price is $24.99 plus tax.
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.
