I'm finally releasing my... University of Toronto Arts & Science Exam Filter. (Maybe I should come up with a catchier name. UTASEF?)
It filters the exam timetable so you don't have to keep Ctrl-Fing through it to see if there are any changes.
On Firefox, you'll need to first install Greasemonkey, then navigate to https://www.alxu.ca/uoft-artsci-exam-filter.user.js to install it.
On Chrome, you'll need to first install Tampermonkey, then navigate to https://www.alxu.ca/uoft-artsci-exam-filter.user.js to install it.
Then, just open the exam timetable and enter your course information and it'll filter the list for you.
