I'm not an expert either...but generally speaking, when someone applies to these kinds of programs, be it for music, dance, art, whatever, it's not enough to be good. You have to be FANTASTIC...and even then, people get rejected, as there's only so much space in the program. And these are people who have taken lessons and practiced, every day since they were like 4 years old.
Also, as mentioned, her grades are terrible. Has anyone ever explained to Taylor that college means more of high school subjects, not just singing all day and following her interests?
My biggest question: what exactly does Taylor expect to DO with that $200,000 degree if she should have it? Become the next Beyonce? Because she seems to have no idea about her future other than she "really likes to sing," and for that, IMO you need just plain luck more than anything else. Is she planning to teach? Work in the industry? as odds are, she will NOT become rich and famous singing. Taylor has no clue and nobody seems inclined to explain it to her.
