Out of curiosity, which subject is it with full tutorials?
I'm one of the tutors for Maths for Biomed (MAST10016) this semester. We've had a record number of enrolments (over 270 students) and the lecture venue is likely to be overcrowded, at least until some students realise that they'd rather stay at home and watch the lectures online

There should be adequate tutorials for all students currently enrolled but I understand that no new students are being permitted to enrol in the subject in first semester. I'm not sure of the situation with Experimental Design and Data Analysis.
For first year maths and stats subjects, another good contact is
Susan Wilson, the undergraduate tutorial manager. The subject coordinator should also be able to help.
Tutors have been instructed to allow extra students in their classes in the first tutorial
only. If you can't get your tutorial sign-up sorted out before the first week of tutorials (that's week one for Maths for Biomed, week two for EDDA), don't panic and just turn up to one of the tutorials anyway. But you do need to be properly signed up for a tutorial because your tutor will be taking your attendance and marking your assignments.
