Thank you for the clarification of your possible living situation when coming to California and why you are leaning towards attending a CC
You have a good plan and the CC to UC transfer pathway is better defined than the CSU to UC transfer pathway. Also TAG will make the CC to UC transfer easier if you meet the requirements. What is important is that you get your parents on board including the eventual transfer costs.
