On my way to an Ivy league?

I have just completed my sophomore year of high school. I have a weighted GPA of 8.21(our school does it out of an 8 point system), I have taken all honors and 2 APs, the hardest classes available to me. I have a 720 on Bio and a 710 on chemistry SAT2's. On the football, winter track and lacrosse teams for my freshman and sophomore years at the highschool. I'm also in DECA(came top 10 in states), and Science Olympiad. I was thinking about retaking chemistry to get a higher grade...but with everything else how do i look as of right now?
