How do I use a QuestBridge fee waiver?

Applying to College
1

QuestBridge’s website says that any finalist for the college match scholarship will receive fee waivers for any of the partner schools, I recently sent in my USC application but could not find a spot to let them know I was a QuestBridge finalist, and QB didn’t give me any codes or anything specific to waive a fee. Does anyone know how QB works in this facet? What should I do if I’ve already paid the USC application fee? And do you know if I receive a fee waiver for all 36 of the partner schools or just the ones I ranked? Thank you to all that respond!
