<p>all caltech tests are taken without a proctor i believe, mostly in your dorm when you have time for yourself. I guess this is one way to relieve the massive amounts of stress the students have. However, to answer the thread, once you are accepted, you will most likely succeed in any field you choose, so in that sense it is very easy to succeed after you get out. Caltech’s courseload is probably more rigorous than other schools, only because they focus so in-depth in certain subjects.</p>
