I have two friends with kids there - one is a brilliant recruited athlete and one is “just brilliant.” Both have found it challenging. One said her intro Physics class covered all of high school physics in the first week. (She took every AP class our high school offered - truly brilliant kid.) It’s not easy for even the smartest kids. I have a kid looking at T20 schools and we’re not even thinking about MIT - she’s very smart but she’s not at that caliber and I wouldn’t want to put her in a position where she’s drowning the first week. Plus, she would never, ever, ever get in! She’s focusing in a few “dream” schools and a bunch of more realistic ones.
