I might drop one of my classes (a strongly recommended course on Assist) in February, depending on how I do on the first midterm. Since the Transfer Academic Update is no longer available after January 30th, is there any other way to update my application? Will it hurt my chances of getting in?
The update is available after the 31st, but there is no guarantee that they will see it.
So, you will need to update it anyways, and email each campus to let them know of the change.
As long as it is not a pre req or drops you in units, I do not see it affecting your admissions decisions.
