<p>1° You do realize you’ll only be taking 3 classes per term (or 5 per semester) and that you’ll be choosing among almost a thousand classes, right?
2° How advanced are you right now? if you are very advanced and can take senior-level classes starting sophomore year, can you still find 1 or 2 advanced classes per term? If so, you should be fine. (Be aware that some senior-year classes at Carleton may be 1st semester grad elsewhere).
3° Actually, virtually all college programs in the US will require you to take 1/4th to 1/3rd in general education. According to the link you provided, you’ll be taking one or two non-science/GE class at UCLA every term of Year 1, 2, and 3. As far as I can tell, at UCLA, you’ll be taking 10-12 classes in general education, with only 3 of those related to math/science. At Carleton, likely 12 classes including 3 in math/science (1 per term for 3 years?). The strength of this program is considered as important as the number of advanced classes you take. That’s why at colleges like CalTech or MIT nobody skimps on general education.
3° You can always try and take more advanced classes at the UMN over the summer, not sure how it’d work though. In most cases anyway you WILL be studying by yourself with a professor’s guidance, typically your senior year, conducting your own reasearch or working on a project. In addition, Carleton is part of the Mayo Scholars program, so you could be conducting research at the Mayo Clinic Summer after your Sophomore or Junior year, doing very advanced work.</p>
