Where do you hope to end up after college? Those are both fabulous options, and there was a thread many years ago (apologies I forget the poster’s name, but someone will remember) who turned down Yale for Vandy, and had a fabulous experience and outcome. I think, IIRC, he was premed, but no matter. He followed his heart and the money, and it all worked out. I believe that yes, even though Cal’s engineering reputation is stellar, if you too are stellar, ad you no doubt are, you will shine and do well no matter what. Both my s’s are engineers. Neither went to college in California, but both live/work there now. Do yo uhave time to visit both again before you decide?
Forgot to mention-- agree with Texaspg-- the recognition of the prestigious scholarship can be a feather in your resume cap.
