<p>GatorEng23, yeah Harvard’s Ma 55 (or whatever it’s number is) is certainly the toughest freshman math class in the nation - no contest. There are, however, easier alternatives that Harvard students can take; there are no easier versions of these classes at Caltech, which is why Durran points them out. Could you imagine taking the three of those along with two other full classes as a bio major freshman year? I sure couldn’t…those people are truly admirable.</p>
