Revelle general education requirements says that if you have IGETC as a transfer student, you need only complete the math and natural science portions of the listed general education requirements (these specify more rigorous math and natural science courses than what is allowed to fulfill the math and natural science categories of IGETC).
For whatever reason, IGETC for UC has a foreign language requirement that is satisfied by high school level 2, even though UC campuses or divisions that have foreign language graduation requirements generally have a higher level requirement than that.
