Students should not use any electronic devices in class, including laptops, tablets, and mobile phones. (Digital paper is fine.) Research has shown that using such devices not only adversely affects one's own performance—students who take notes on a computer process the information less completely than those who take notes by hand—but that it also adversely affects the performance of other students whom it distracts. (See here and here, for example.)
Students who for some reason need to use electronic devices in class should speak to the instructor.
Performance on the mid-term examination, held in class on 13 October, the final examination, held on 19 December, at 9:00am, and the seven problem sets will contribute to determining a student's grade for the course. The grade itself will be determined by a variety of factors.
Problem sets are due in class on the day specified. We will not accept late problem sets, as late sets make the graders' task much more difficult. On the other hand, we are quite prepared to grant extensions, so long as they are requested in advance, that is, by no later than 5pm the day before the problem set is due. (Such requests should be directed by email to the instructor, cc'ing your grader.) Extensions will not be granted after that time except in very unusual and unfortunate circumstancess.
Because we are so reasonable, exploitation of our reasonableness will be taken badly. Do not make a habit of asking for extensions. We will grant one, and maybe another, but that is about as far as we are prepared to go, unless you have some very good reason.
The grading scale for the problem sets is described on the problem sets page. The assigned problems for each set can also be found there.
Let me emphasize again something said above. As with any mathematical subject-matter, it is impossible to learn this material without doing a lot of exercises. The book contains many more exercises than are assigned, and students are encouraged to do additional exercises to improve their understanding of the material. Students are also encouraged to work on the problems together—though, of course, submitted material should be a student's own work.
