I don’t know about CalTech, but Harvey Mudd doesn’t require calculus. "</p>
<p>Caltech doesn’t require it either though it is recommended and I would imagine most applicants have taken it. I think Calculus is really cool and would recommend it as an intellectual exercise, but statistic is much more likely to be useful. (I had to take Calculus for architecture school, but have never used it, even for the Statics courses I took there.)</p>
