What are my chances?

I’m going to be a senior in the upcoming school year, and my top 2 college choices are Georgetown and William and Mary. However, I’m unsure of my chance of admission to either.
My SATs are as follows:
CR-600
M-690
W-680
SAT subject tests:
Chemistry-710
Math 2-760
U.S. History-680

Nighthawk aquatics (fish tank management for my AP chem class)

Do I have a shot? I’m afraid my SATs will hold me back
