if you are in UG still, either way once u get an acceptance (in spring for example) you will have to send your entire transcript in again for backkground checks or w/e. so eventually schools will see your fall grades anyways, so u may as well send them in during academic update period.
academic update is optional (as it says on your aadsas app), but if u have planned in progress courses listed on your app , im sure schools will want to see them, especially bc theyre interviewing u after dec1st. aka maybe they waited this long to interview u bc they wanted to see how u perform in fall courses.
you shouldve been keeping your fall grades up for academic update....
