You are encouraged to work in groups on your homework; this is generally beneficial to your understanding and helps you learn how to communicate clearly about mathematics. However, you must write up all solutions yourself. Moreover, since crediting your collaborators is an important element of academic ethics, you should write down with whom you worked at the top of each assignment. You should also cite any sources (other than lectures and the textbook) that you use.

Exams: The exams are non-collaborative closed-book exams. You are not allowed to use books, notes, or any electronic devices (such as calculators, phones, computers) during the exams. There are two in-class midterms and a single final exam on the following dates.
Exam Date Time Location Practice exams (old)
Midterm 1 10/19 2-2:50pm PAB 1434A a, b, c
Midterm 2 11/16 2-2:50pm PAB 1434A a, b, c
Final 12/5 3-6pm PAB 1434A a
There will be no make-up exams. Attending the final exam is mandatory. In particular, note that university policy requires that a student who misses the finals be automatically given F, unless the absence is due to extreme and documented circumstances, in which case, if the performance in the course is otherwise satisfactory, the grade might be I.

Grading: Numerical grades will be recorded in the MyUCLA gradebook. A composite numerical grade will be computed by the following formula.
Max(20% HW + 20% Midterm 1 + 20% Midterm 2 + 40% Final, 20% HW + 20% Best midterm + 60% Final)
A curve compatible with the department guidelines will be applied to the composite numerical grades. If you believe a problem on a homework or an exam has been graded incorrectly, or that your score was not correctly recorded in the MyUCLA gradebook, you must bring this to the attention of the instructor within 10 calendar days of the due date of the assignment in question, or the date of the exam, and before the end of the quarter (12/9). Grading complaints not initiated within this period of time will not be considered. Please verify in a timely manner that your scores are correctly recorded on MyUCLA.
