<p>UCSD is the only one that has the 6 colleges like that. For all UC's (as well as UCSD), there is a place where you choose the major(s) you want to apply for at that UC. The major may be in a certain college at the university. For example, when I applied to UCLA, I applied for Electrical Engineering, and this was in the engineering college. If you apply for most other things, you will be applying to the college of letters and sciences (CL&S). SO basically, you just choose the major you want to apply for, and this major may mean you are applying to some certain college there. It's different from the 6 college thing at UCSD. Like even UCSD has an engineering college, which you would apply for if you were an engineering major (automatically by choosing that major).</p>
