Hi Gabe,
As a grad of CSU Fresno myself, I *feel* your pain! Is Dr. Rodemeyer still the pre-med advisor there? He should be able to give you some data on the numbers of CSUF grads who get into med school.
However, bear in mind that while the "UC is better" mentality is alive and well in California, I *highly* doubt it makes a significant difference in medical school admissions, all else (grades, test scores, etc.) being equal. So, if this is your only reason for transferring, I'm not sure its warranted.
I'm sure you'll find that acceptance rates to med schools from UCs *are* higher. Then again, admission standards for UCs are higher than CSUs, they have access to medical faculty at their institutions and more resources for letters from "known" medical names,etc. There *will* be advantages to going to a UC, but it will be substantially more expensive (especially if you are living at home right now), you will likely have much larger classes, etc.
I'm sorry I don't have any numbers to back me up, but it sounds like what you want to know is, is there a significant difference in medical school admisions among students with same gpa and MCAT scores as you have as a function of their undergraduate university? See if you can get the data from the CSUs and UCs pre-med committees.
Best of luck!
