It's a pretty new service, and actually helps you to build your timetable by highlighting potential clashes for tutorials / labs / recitations.
So, barring any further exceptions / additions (notably, I believe, CS4251 and 4254), here goes:
Tuesday
1000 - 1200 CS4254-L(1) [0] S16/307
1400 - 1500 CS3255-T(1) [0] S16/305
Wednesday
1000 - 1200 CS4251-L(1) [0] S16/405
Thursday
1000 - 1200 CS3255-L(1) [0] LT34
Friday
