It is amazing how “holistic” the UF admissions policy is… I remember my son telling me his application kept “changing” and that he did nothing to it. The major changed (to non-descript) and not because of anything he did.
If the admissions is based on what they say it is… why are they manipulating the applications and then “holistically” selecting their students? I graduated from a lot of schools… including Ivy League… UF wasn’t one… guess there are far better schools out there who won’t “randomly” put my son in a lottery and then tell him he’s admitted to online school! He did get a full ride to somewhere better. UF loss. And some of the even more talented students are going somewhere else!
Congrats to your son! Glad he’s been accepted to a great school. 
UF normally doesn’t “change” someone applications (why would they?), so I have no clue what was going on. Why change major, when it’s not even considered by admissions? Weird.
@SwimIBMOM Sounds like your son was admitted to PaCE. Those students have their major reset so they can update it if they choose to confirm enrollment. Congrats on the full ride.
