I was recently looking at the common app and saw that UPenn allows an art supplement. I have played guitar for the last 9 years and am quite advanced. Although I am applying to the wharton program and branding myself as a finance major, should I still submit and advances guitar piece? I would send a 3-5 minute video of me playing and singing a hard guitar piece (neon live by John Mayer la concert).
I applied to Wharton last year and found that when applying for specifically Wharton, they don’t give you space, at least explicitly, to add in an arts supplement.
You could ask to send one, but I figured that it being a preprofessional business school they might not be that interested in taking time to review art supplements
Not sure if it is allowed or not for Wharton but IMO for an arts supplement to be helpful at a top tier college it should be of an extremely high (conservatory level or close) level. A lower quality supplement could take away from your overall application. Have an independent professional listen to your playing and give you an honest evaluation.
