You do not state what is your college budget?
SBCC’s Cost of attendance is $25,212 which includes room and board. For OOS students you need to add another $8978 for a grand total for $34,190. Very pricey for a CC for 2 semesters worth of classes to qualify for priority as a CC transfer. Then you will be paying $67K/year for her to attend a UC?
I do not understand the logic in coming to CA to attend a CC and then Transfer. If she is a competitive student, then there will many 4 year university options with merit as a Freshman applicant which may be less expensive then 1 year at a CA CC and 2 years at a UC.
