Nicole is right that you have to switch Math 1ZZ5 to C03, but then it conflicts with your Monday English 1A03 tutorial time. Stupid 8:00 starting time!
Anyway, just change your English 1A03 tutorial to T9,10,11,12,13,14,15 or 16 and all will be ok. That just shifts your tutorial from 18:00-19:00 to 21:00-22:00. I know it sucks.
