<p>im planning on going to carnegie mellon next year for physics . I want to major in physics or computer science . Currently im in love with physics and thats what i want to do , but i also i like computer science and they switch back and forth . if i go to cmu for physics and dont like it , How hard is it transfer to their computer science program .. because their known for their computer science . I think their ranked right next to MIT , Stanford , and UCBerkley?</p>
