Homework

Homework policy: you may discuss problems amongst yourselves, but you should write up what you hand in.

I (due Jan 16): Solution. Average: 56.9/80; standard deviation: 15.7.
II (due Jan 23): Solution. Average: 58.7/80; standard deviation: 14.5.
III (due Jan 30): Solution. Average: 61.5/80; standard deviation: 11.9.
IV (due Feb 6): Solution. Average: 58.3/80; standard deviation: 12.4.
V (due Feb 13): Solution. Average: 50.3/80; standard deviation: 15.1.
VI (due Feb 20): Solution. Average: 58.8/80; standard deviation: 12.6.
VII (due Feb 27): Solution. Average: 47.4/80; standard deviation: 16.0.
VIII (due Mar 5): Solution. Average: 54.8/80; standard deviation: 9.2.
IX (due Mar 12): 15.29 Solution. Average: ; standard deviation: .

Here are guidelines (some of which should be obvious, I hope):

Name (printed clearly) on top of page.
Box in final answers, especially for problems with multiple (a, b & c) parts.
Label multiple parts of problems (a, b & c) clearly.
List assumptions clearly.
Don't write all your answers on one sheet of paper.
Staple your answers together.

Quizzes

There will be five hourly exams are closed book, no notes. Bring pencil and calculator to all exams.

I Solution Average: 10.2/20; standard deviation: 3.8.
II Solution Average: 10.9/20; standard deviation: 2.6.
III Solution Average: 11.00/20. standard deviation: 3.4.
IV Solution. Average: 13.3/20. standard deviation: 2.9.
V Solution. Average: /20. standard deviation: .

Final

The final will be on Monday March 17, 11:30 am-2:30 pm. Closed book, one letter paper sheet of notes that you have prepared. A make-up exam will only be provided for medical reasons with proper documentation from a physician. The final will cover the material lectured during the course. Equations you should know.

Grading policy

Method A: Curve based on: homework 10%, 4 best of 5 exams 40%, final 50%.

Method B: Absolute scale based on final: A > 80%, B > 70%, C > 55%, D > 40%.

Your grade will be computed by methods A and B and you will receive the higher of the two. I may rescale the different components (homework, quizzes, final) separately to arrive at the final grade.

Cheating

I remind you of UCSD's policy on academic dishonesty.
