PTCAS will give you a chance to update your grades, if you have classes that are still in progress. But i'm unsure about updating after admissions (by that do you mean results, i.e. accepted or denied). I graduated from UPS for my undergrad. They did have some undisclosed financial help for those who needed it. That was how I was able to pay for my BA. They have scholarships from past alums that donate to the school specifically for students who either qualify for financial help, excellent GPA, majors, or even diversity. Also, I believe that the APTA website can show you some sources for scholarships for PT school.
