They probably will be requesting Winter Qtr grades. Recently, someone with the TTP and applying for Fall 2018 received a transcript request to submit Winter Qtr grades. The person had a 3.9 GPA (2 A’s, 1 A-, 15 units) in the freshman Fall Qtr and previously submitted the transcripts. For Winter Qtr, this person has 3 A’s and 1 A- (20 units) and will submit. USC probably wants more history than just 1 quarter of grades to make a determination.
