I do not trust the Princeton Review’s methodology. For example, in Fall 2015 Agnes Scott College only offered three classes beyond Calc II (aka AP Calc BC). Frankly a junior who only took precalc in high school would likely exhaust the offerings. Of course a student could drive Georgia Tech or Emory, but that’s annoying and when you’re taking 3/4 of your classes at another school, you might as well transfer.
