How can I get into Georgetown?

Hello,
I am a rising junior at a public school in Maryland. I want to major somewhere in science (something probably related to biology, chemistry or health). I know Georgetown is not the strongest in science majors, however, I want to go to Georgetown.
Currently

GPA: 3.88
Weighted GPA: 4.5
(My school does NOT have exams. Our school year is divided into 4 quarters, 2 quarters a semester. If you get a B one quarter and an A the next, it is an A in the semester. If you two A’s it is an A and so forth). I’ve gotten A’s in all my classes (semester wise) in high school, but the high school courses I took in middle school, I got B’s, lowering my GPA.

AP Chemistry: 4
AP US History: 4
AP NSL: 4

Chemistry SAT: 730

I am planning to take the Biology SAT and MATH 2 SAT. I am aiming for at least 1500 on SAT.
What more can I do to get into Georgetown?
