My D also considered the Thornton School of Music/USC. The school allocates a lot more of their funds to graduate students so don’t be offended. USC music graduates are all over the LA music scene so the school has a clear and dominant position when it comes to job placement. I would wait for your financial aid package before deciding. Congratulations on your acceptances. This is a very difficult decision for you but most would be envious to be in your position. Good luck!
