Appeal Essay

Hi there, I have a family member that would like to appeal to UT Austin but with a different major from what they originally chose. They're not too sure how to approach the essay and would really benefit from some sort of counseling and essay editing. They're willing to spend some money on this as UT Austin is a top choice for them and they want to give it their best. We don't have anyone in the family who's gone through this process so feeling pretty lost, even with some Google searches.

If anyone knows anything about the appeal process, what's expected, and if there's any reasonably priced resources to help with this, would greatly appreciate it!

Any other advice regarding this would also be great!
