<p>Last time I checked (quite awhile ago), BioE looked like a subset of ChemE. ChE at Caltech is much harder and more quantitative than what any normal premed program could possibly look like. If you like math (ie, you assume you would find biology boring), you might enjoy Caltech. That situation described me. By the way, I found Caltech offers pretty good premed support. During the summer, they help arrange preceptorships or rotations with a few hospitals. I did a few weeks with the Children’s Hospital in LA. I then realized that I enjoy doing research much more! :)</p>
