I got my OSAP release probably about a week or so ago and was told to check MUGSI in a couple days to wait for it to be updated. I logged on a week later and it shows my full tution and OSAP hasn't been added. Do I need to do something specific for OSAP to come up on my student account? Or should I wait? Or go into the student loan office? I just don't want to get interest and have to pay that, I know I got my osap and it's been released I just wonder if I'm missing something...

Thanks in advance for the help

I would call or check up with the Student Accounts and Cashier's Office. I'm not sure about the interest part which depends on your method of payment and how much you owe.
On your student account it only shows how much OSAP money has been given to you/deducted from your tution. As long as you follow your payment method (pay your monthly installments for the Monthly Payment Plan) then you shouldn't worry about interest. I would still check up with them though.

it actually took a long while for anything to show on my account.. it only updated for me last week and i picked up my osap at the end of august
