CC to UC/CSU transfer is a great option if you want a specific UC/CSU and want to save money. 6 UC’s have TAG which guarantees you an acceptance if you meet all the TAG requirements for one of the UC Campuses (UCM/UCR/UCSC/UCD/UCI and UCSB).
CSU’s offer the AS-T/AA-T which guarantees admission to one of the CSU campuses (not particularly your choice campus).
If you are thinking of going into the Medical Field, either MD/PA/Dental etc… Prestige/Ranking of your Undergrad school will make little difference. You want to attend a school with your Major, chance for a High GPA, access to Medically related EC’s and good Pre-Professional advising. CSU Fullerton and Long Beach can offer you these things so do not write them off since they are viable options.
Biology majors are a dime a dozen, so I would reconsider and select another major option depending upon where in the Health/Medical field you have interest.
