So do we have to update quest with the winter 2018 courses we’re taking, before Jan 31st as well?
I don't know for sure but I think they'll look at your Fall 2017 grades just to make sure that you've kept your average up (it's a chance for you to show that your grades have improved maybe). Maybe similar reason to why they want to see your 2018 grades if you're accepted (to make sure you didn't completely slack off or something).
