What are my chances?

Hii, I want to go to Georgetown and want to hear what you think my chances are:
I’m an international student in a really selective and respected high school (known school by the colleges around the world and they have specific scholarships etc)
-I think my IB predicted grade will be 39/40 over 45
-SAT: I took the SAT once and I got 780 in math and pretty low in reading and writing. I’m taking it again to improve my reading&writing, so that I can superscore and get something between 1500-1550.
-I will take math 2 and 2 other SAT subject tests.
-A lot of extracurriculars in many areas (a lot of community service hours and many leadership positions)

Honestly, you can be harsh if I have no chance so I don’t waste time+money by applying. Also what are safety schools for me?
