In my D’s main friend group are all of the types you can imagine: very Republican and very gender identity conscious; very ‘whatever’ and very driven; lotsamoney, some money and absolutely no money.Etc. Some work super hard, others just work hard. This particular gang don’t get caught up in the occasional waves of political angst (there is one going on now) or the super-partiers (yes, there are some), but they are happy to live and let live. If you are happy enough to do that you will be fine.
And for pre-med, Vassar is super: very supportive, not cut-throat all- but very rigorous so that you are well and truly ready to make a strong application to med school, and thrive when you get there.
