UCI has a lot of weird requirements for its CS major that community colleges do not cover, so you may have to spend a few quarters after transfer to “catch up” on CS courses, which can delay graduation.
You need to ask UCI if your combination of Southwestern ENGL 115 and SDSU 200 will fulfill UCI’s lower division writing requirement, and if that is required to complete before transfer (even if not required before transfer, it is desirable to complete it before transfer).
