Sort of a joke that getting an “A” in colleges like Harvard and Yale is easier than Boston College or Ruetgers.

I've taken classes at a few different schools including Harvard. This is absolutely not true. You don't really have to be smart to do well at Harvard, although it helps, but you absolutely do have to bust your ass (in a way you do not at other top-tier schools as long you have some familiarity with the subject going into it.)
