Welcome to the wiki website for the MAT315 course: Introduction to Number Theory. You can edit anything by clicking on the "edit" button in the right top corner. Your participation here is not graded, but hopefully is very useful to other students and to yourself.
final exam grade
was adjusted according to formula 27+0.73*x, where x is the original grade. The mark you are going to see on ROSI is the same as the mark in the "course mark" column on the portal.
--- post any questions/problems you have here. Either me (Yuri) or one of the TAs (Misha, Lucy) will answer them as soon as we can.
(includes the last midterm and solutions)
(Yuri's office hours are on Thursday 10-30-12:30 in BA6283, Misha's office hours will be on Fridays, BA4010, 12-2)
--- if you aren't sure how editing works, follow this link and edit the page there.

For some reason some of the videos appear to be in slow motion after I upload them to youtube (at least on my computer). The original files are fine however. Send me an e-mail if you need them.
