With all due respect you’re not “probably going to get accepted to all of these”. The kid saying that is a junior in high school so I wouldn’t take what they say to heart (no offense gatsby). If you read through CC over the past few months you see a lot of heartbroken students who were told the same thing and didn’t get into a single one. The Ivy leagues (and their equivalents like MIT) are extremely competitive even for top tier students with incredible extra curricular activities. That being said, you are a competitive applicant, so I think you would get into 1 or two of the top tier schools, especially if you get your SAT up a little bit. I’m happy to see your college list includes realistic match and safety schools as well :). I recommend looking into and applying ED to one of the top schools that you really love as well.
