The grader will assign each homework a grade out of 10 with only a few problems being graded (3 or 4 or so). There will also be points awarded for the overall completeness of the assignment. I won't be telling you in advance which problems are being graded though..

Do collaborate on the homework if you like, but write up your own solutions. I also strongly advise you to have a look at the UB Academic Integrity Policy, as it very much applies to this class.

And by all means drop by at office hours if you need a hand.

We're having two take-home exams. The due dates are as follows

Exam policy:

Those are the due dates. I will post the problem lists a few days before, so you will have plenty of time to work on them.
We'll drop the two lowest homework scores.
If you have any questions, don't hesitate to email me.
