I went to CSU, applied to med school 12 times, and got rejected from every school. My parents sold all four of their kidneys to pay for my application expenses. After months of working the phones, I finally got a meeting with one Dean of Admissions. Dean Nusselbaumer from Big State School of Medicine. I sat down in the leather chair across from his cherry desk, and said, "Hello, sir. I'm XX. I did my undergrad at CSU and earned a 3.9875 GPA." At that point, he SPIT IN MY FACE! He literally used his mouth to propel sputum at my face! He pulled a K-Bar on me and got all Crazy Marine and chased me out of the admissions office.
The point is this: It doesn't matter where you go to college. At all. Most science that is taught in your entry level science classes and tested on the MCAT has not changed since before you were born.
