“I really want to go to a top 5”
I am wondering: WHY?
I did attend two top 5 universities. One for my bachelor’s and one for my master’s. Classes are a lot tougher than anything that I every saw in high school. Classes go really fast. There are tons of homework. Tests and exams are tough.
There may be some math majors at MIT and Caltech who once got a C in a languages class or an art class. I doubt that there are many students at either of these two schools who ever got a C in a math or science class in high school.
If you attend a “top 100” university and get a lot of A’s and very few B’s for four years, then the “top 5” universities will still be there if you are looking to go to graduate school.
