Transferring to a UC or San Jose state with 2.93 GPA for history major.

I’ve finished my second year at a California community college right now, and for the past two years my major has been chemistry. but during the summer I’ve decided to change my major to history since I realized my heart’s not in science and I am more into history stuff. But due to the bad grades from the past science classes that I took, my GPA is at 2.93.
I am going to be in community college for another year and I still have enough time to finish the history courses that I need in order to transfer to a university with a history major by next year.
I am really interested in going to either UCM, UCSB, UCR or SJSU and I’m just wondering, what are my chances of getting into those UCs and san jose state with a 2.93 GPA for history major? And also, will my sudden change in majors and the fact that I took several science classes even though my major is history affect my chances of getting into the school?

The past several fall semester admission cycles at SJSU have had threshold GPAs for the history major ranging from 2.30 to 3.00: http://info.sjsu.edu/static/admission/impaction.html

You can use http://www.universityofcalifornia.edu/infocenter/transfer-admissions-summary to get transfer admit rate by GPA range and UC campus, though it does not offer stratifying by major. UCR, UCSC, UCD, and UCM all appear to be in the 40-60% admit rate range for 2.80-3.19 GPA transfer applicants for fall 2014. UCSB was at 23%.

Thank you so much!

You’re eligible for UCM TAG right now, and if you bring your GPA up, at others as well:
