Well, I think the main reason they stopped requiring them is that the student feedback indicated they found the three a week a bit overwhelming. The AEP still continues to monitor its students and try and find solutions for them if they are not performing well...and in the APC meetings at the end of each term, admin does ask if a student is making use of the resources available if they are performing badly...and it doesn't look too good on them if they haven't participated at all. This is constantly under review and may change back again one day.
