Office: MS 2905
OHs: Monday 1:00pm-2:30pm (Michael), Wednesday 1:00pm-3:00pm (Will), Wednesday 3:00pm-4:30pm (Michael)
LECTURES: MS 5138; MWF; 12:00pm-12:50pm.
DISCUSSION: MS 5138; Tuesday AND Thursday; 12:00pm-12:50pm

Every fourth discussion is mandatory since a quiz will take place and quizzes count towards your grade.

The other discussions are not mandatory, but I hope they will be useful. The format and focus of the discussions will vary a little. They will run in cycles of 4.

Discussion 1: this discussion will be more like you are used to. It will be a chance for you to talk about problems that you have with material covered in class, for Will to expand on material covered in class, and for you to see more relevant examples.

Discussion 2: this discussion will focus on proof-writing. You will divide in to groups of three to five, and work on black-boards around the classroom. Your goal will be to create a proof, and to help each other refine it until it is perfect or as good as you can make it. When you're done, you will show the group next to you and they will comment. Will can oversee everyone, and help steer you away from unproductive thoughts!

Discussion 3: you will receive your homework back. You can discuss problems with the homework. The rest of this discussion will be more like a regular discussion, unless the second type of discussion is popular, and then we can make it more like that.

Discussion 4: you will take a quiz. This discussion is mandatory.

HOMEWORK: There will be 5 homeworks. They will be turned in at the BEGINNING of FRIDAY LECTURE (12:00pm) in weeks 1, 3, 5, 7, and 9. These homeworks will also serve as preparation for quizzes, but you should NOT expect to see exactly the same problems on a quiz.

Most of the graded questions will be less proof-intensive. You should come and talk to Will and me for thorough feedback on your proof-writing. That is the ONLY way to be sure you will score highly on a quiz because we grade the quizzes, but an undergraduate grader grades your homework (UCLA's idea, not mine).

QUIZZES: There will be 5 quizzes. They will be during your THURSDAY discussion (12:00pm-12:40pm) in weeks 2, 4, 6, 8, and 10.
MIDTERMS: There will be NO midterms since the homework and quizzes will count towards your grade.
FINAL: There will be a final exam on Wednesday, March 21, at 8:00am-11:00am.
GRADES: Your grade will be determined by your position in the class. Your score will be the higher of the two scores calculating using scheme 1 and scheme 2.

Scheme 1... best 4 homeworks: 2.5% each, all five quizzes: 10% each, final: 40%.

Scheme 2... best 4 homeworks: 2.5% each, best four quizzes: 10% each, final: 50%.

Any issues about grading for quizzes must be addressed within two weeks of the grading. After that time no score changes will be allowed. Grades will be available online through the myUCLA website.
