Hi,
I found another community college that is offering a lot of online classes which is very good for me to take General Courses online in that college. Do UCs care if I take some of my courses online in another college when I want to transfer?
Typically no. There are exceptions in that you should complete full sequences of courses at one college most of the time, but so many people do this to fulfill gen ed requirements, etc, esp. when they can’t get into classes in their own CC. UCs know how it is, the situation at CC can be difficult with getting classes many times, and they don’t look badly on going to two or more different CCs at all.
No they don’t. There are a number of reasons why someone might take classes at 2 (or more) colleges concurrently.
As said above, however, it is best to complete sequences like calculus at one school.
