Due to lack of standardization of CS courses among the UCs and CSUs, it is very common for CC students in California to need to “catch up” on frosh/soph level CS courses after transfer due to lack of course articulation between their CCs and UCs and CSUs. It is sometimes a little better for CCs near a particular UC or CSU, since the CC sometimes copies the courses from the nearby UC or CSU.
Engineering majors sometimes have similar issues with courses other than math and science. Frosh/soph level math and science courses are typically more standardized, so they match up better and are less likely to be needed to be taken after transfer.
