<p>Well I am not a professional in these, but as far as Stanford goes I would say you have slim to none chance. Because Stanford might have the lowest Transfer acceptance rate, so unless they really like you for something unique, I would say its almost impossible, but I would never say anything is impossible.
Also with UC’s if your not from Cali I think it is very hard and Berkeley I know has good Computer Science, and Engineering so UCB would be difficult too.
Good luck.</p>
