Grading: All scores and grades will be available on MyUCLA website.
The course grade will be determined by the cumulative percentage of scores at the end of the quarter.
This is calculated by taking the BETTER of the two schemes:
Homeworks: 15%, Two midterms: 15% each, Quizzes: 10%, Final: 45%.
Homeworks: 15%, Best midterm: 20%, Quizzes: 10%, Final: 55%.
Difficulty: This is an introductory course in Discrete Mathematics.
The students are expected to learn the theory and solve problems on the homeworks.

We will follow closely selected sections from the textbook.
An approximate schedule of lectures is given on the official department

Discussion Sections
The discussion section will be a time for students to get help with homework and gain
additional mastery of the problems. While attendance is not required it is strongly
recommended that you go. You should go to the section which you are enrolled;
changing section is allowed only by permission of TA of the section you are switching to.
Collaboration Policy
For the homeworks, you can form discussion groups of up to 5 people each.
In fact, I would like to encourage you to do that.
You can discuss problems but have to write your own separate solutions.
You should write the list of people in you group on top of each HA.
Cheating
Cheating is a serious violation of UCLA policies. Please read here
and here. Students caught cheating will be reported and suffer the
consequences. Do NOT cheat!! Don't even think about it!
Complaints
Any issues about grading for homeworks or exams must be addressed to your TA
within two weeks of the turn-in date. After that time no score changes will be allowed.
Issues with Final and the final grade must be addressed to the instructor.
