<p>I like your attitude, but you should proceed with a bit of caution before coming to Caltech as a premed. </p>
<p>Realize that the largest part of the difficulty will be in the math and physics core, and if you’re not pretty qualified in those two areas, it’s not unreasonable to expect Cs or even Ds in these courses. </p>
<p>On grades you would have to take: electromagnetism, statistical mechanics/waves, quantum mechanics, multivariable calculus, differential equations, and probability and statistics. </p>
<p>If you’re reasonably comfortable with taking those courses, then you’d probably do fine as a premed, and Caltech is a great place. Otherwise, there may be better alternatives.</p>
