What are we learning?

You can check out the syllabus. The less than 140 character synopsis is:

Induction, sets, functions, relations, recurrences, graphs and lots of counting (in multiple ways)

A, B, C, D, E or F

You have to get through about 8 or 9 homework assignments (weekly!), 2 midterms and a final examination. The final will be cumulative, but with more emphasis on the material taught in the later part of the quarter. You will each be awarded a numerical score based on the higher of the following two schemes:

Scheme I Scheme II
Homework 15 % 15 %
Midterm I & II 25 % each 30 % (best of two)
Final 35 % 55 %

The resulting numerical score will be converted to a letter grade based on class ranking following departmental guidelines. Roughly 28% of the class will get As, 35% of the class will get Bs and 28% will gets Cs. There are no extra credit options. All scores will be recorded in MyUCLA, which you are asked to check from time to time to ensure there are no oversights.

More about homework

A homework set will be assigned to you each Wednesday at the beginning of class which will be due exactly one week later (i.e. by the next Wednesday, 10:00 AM). It will consist of practice problems (which will not count towards the grade) and mandatory problems (which will count towards the grade). Amongst the mandatory problems, selected problems chosen by the instructor will be graded. Late submissions will not be accepted and you will get a score of zero for such work. However the lowest two homework scores will be dropped while calculating your grade.

Your name must be clearly displayed in the top right corner and be stapled if there are multiple pages. If your TA has difficulty in reading your answers, he/she will give you a score of zero, so please ensure you write legibly and neatly. You can work together (in groups of less than five), but please write up the solutions on your own. Also indicate the members in your homework group.

Grading disputes

If you feel that a mistake was made in grading your homework or that these scores have been incorrectly inputted into MyUCLA, bring it to the attention of your TAs within 14 days of the due date of the homework. If you feel that a mistake was made in grading your exams or that your exam scores have been incorrectly inputted into MyUCLA, please ask me (not your TA!) within 14 days of the exam date.

Any complaints received later will not be considered. Be aware that a re-grade means that your test will be graded from scratch, and it is entirely possible that you will receive a lower score than originally given, if I decide that the original grade was too high.

Asking (the right) questions in Piazza

To sign up, please follow the link -- https://piazza.com/ucla/winter2017/math611.

You are encouraged to use the discussion forum in Piazza to ask both the mathematical and admin questions. This avoids repeat questions and will probably get quicker responses. Try not to email me unless you feel the question is confidential and requires a non-public answer. While asking math questions, ensure you are including all the relevant information in the question. (For instance, do not simply refer to Question X in HW Y but state what the problem is)

Exam dates

Midterm I Jan 30 10:00-10:50 A.M
