What makes Caltech so notoriously difficult?

<p>Uh, I’m the parent of a student admitted to Caltech. I’m not even sure what language you just wrote in! LOL</p>

<p>I’ll pass this along to my son and see if he’s able to take a stab at it. fwiw, he says he’s looking forward to being challenged and working hard wherever he goes, so all is not lost, hopefully.</p>

<p>Also, my son is a URM but my guess is that he has the background to do the work at Caltech, MIT, etc, and would have been admitted based on his performance on national math and physics competitions as well as his physics research and math/physics college coursework. I could be wrong, though. I always though Caltech would be too intense but he’ll have to make that decision for himself.</p>

<p>Thanks for the input, T.A.D.</p>
