Chances for Ivy Leagues a junior with perfect SAT and ACT?

I’m required to do a summer project by my school anyway, and it won’t take the whole summer (only going to be there for 2 weeks + there is a research component), so what would you recommend instead?
Also, how would one go about studying for the TSA?
Honestly I’m somewhat undecided but leaning toward business. I’m not exclusionary toward anything but Ivies, I understand they will always be a lottery. Also interested in living in a Northern city, that is just te kind of lifestyle I enjoy, so Ivies fit into that for the most part (yes I know Yale and Princeton are not urban, I just put them on there for kicks). I know my ECs are bad and that’s why I came on here to get some possible advice and see what my chances would be anyway, just out of curiosity.

I would also like to thank everyone for taking so much time to read my post and write all of this out, it has been really helpful and somewhat of a reality check for me and I really appreciate it.
