What should I do to better my chances.

Hi I'm a ninth grader who wants to apply for MIT.

Right now I can't really say what my GPA will be but i think it's easier to get a 4.0 in my district than others)

Based on other tests I have taken I think I'll get around a 1530-1550 on my SAT

I wanna get onto the varsity tennis team which I have a pretty good shot(I am currently the number 1 boy on freshman)

I am also a violin player aiming for all region in the next few years.

I am about to get Eagle scout(I am life right now)

I am planning to take around 8 honors and 10-12 APs(I signed up for a DE this year for algebra 2 but I'm in honors instead and my counselor isn't responding to my questions about it)

I want to aim for a position of leadership in a robotics or CS club(the first meeting for CS is in like 15 minutes lol)

it says I have a 16% chance to get into MIT, what could I do to make it better.

Idk if I should early admit because I don't know if I have to put less AP's on my app.
