@Hoping2 Yes, you may get some harsh critique on CC, but it is generally meant to be helpful. Having been on CC for many years I have seen way too may people overestimate where they will get in, apply unwisely, and end up left with no viable college options. Nobody wants you to be in that position.
Your academic stats puts Columbia more or less out of reach – at best it is a real long-shot. https://undergrad.admissions.columbia.edu/classprofile/2022 Columbia accepted 7% of applicants last year. There is not room for all of the very well qualified applicants – the school routinely has to turn down people with perfect GPAs and standardized test scores. Keep in mind that the bulk of students who get in with lower test scores are “hooked” applicants (ex. recruited athletes, children of large donors etc.).
That said, good luck with your application to Columbia – by all means give it your all. But also be sure to craft an application list that includes affordable (check net price calculator) match/safety schools given your academic stats.
If you want to research other schools I recommend you get your hands on some good college guide books (ex. Fiske, Princeton Review) and start reading up on different schools. These books are often in the guidance office or library.
