The one thing that I can’t help but notice is that when I’m reading your stats, I can’t seem to figure out what kind of person you are. You’re extra curriculars are all over the place. Ultimately, you have a strong profile in terms of grades and scores (I wouldn’t worry about your essay, since it doesn’t matter for your major). What I would recommend is to try to brand yourself a bit more. You are a STEM person, which is great, and you like to sing. That’s a persona right there.
Now, make a story with your extracurriculars. Looking at how they are now, they look like they were done to try to buffer your application. For example, “Peer helpers club”, along with being a member of senior councilor, seem to be clubs that you joined to boost your EC’s. I wouldn’t even mention them in your application, as they detract from the more important ECs.
If you work on marketing yourself better, I think you have a very good chance when applying to any of these schools. Just remember that Harvard is a reach for everyone, and there’s no guarantee for any of the tippy top colleges.
Best of luck!

Your best choices for CS/Math are
Cornell
RPI
Harvey Mudd
@GoRedhead it doesn’t make sense to put Swat and Haverford in the reach category but Pomona and Mudd in the match category. Here are their acceptance rates for class of 2021 and middle 50% ACT composite (from CDS for class of 2020):
Pomona - Overall acceptance rate 8%; ACT 31-34
Swarthmore - Overall acceptance rate 10%; ACT 30-34
Haverford - Overall acceptance rate 19%; ACT 31-34
Harvey Mudd - Overall acceptance rate 14%; ACT 32-35
They all belong in the reach category and Mudd has a self selecting applicant pool and is an even tougher admit than the relative acceptance rate suggests. Also if OP is female then that helps a little at Mudd but hurts a little at the others. http://talk.collegeconfidential.com/discussion/comment/20616259/#Comment_20616259 (data about male vs female acceptance rates at LAC’s from class of 2020, I think)
^All four of those schools have a self selecting applicant pool.
Which colleges did your parents attend for their undergraduate education? Those schools are really the only ones at which you have legacy status unless the others consider grad school legacy too.
All your schools are reaches save Oberlin, RPI, U of R, Case, and Reed (Vassar and Hamilton too, maybe, but they emphasize the essays). A good ACT score will only get you so far. Write great essays and you’ll be admitted to plenty of your reaches.
