<p>I think it’s normal to question your choice when you have great options. My son was in the same situation two years ago. He had hoped to attend Princeton because he wanted to major in Engineering but also have access to an exceptional liberal arts experience. When he was accepted to Princeton, Harvard and Yale, all such amazing choices, he started to question what he should do. He revisited each, and although he enjoyed Visitas at Harvard (he didn’t get a good feeling at Yale, in part due to the Policeforce holding a protest outside of the admitted students/parents event held in an auditorium in New Haven about the violent crime statistics and wanting higher pay) Princeton felt right to him. Once he made the decision, he’s never regretted it and loves Princeton even more than he thought he would. He decided after his freshman year to switch from MAE to ORFE due to the amazing economics classes he took his freshman year. The point is that if Harvard is what felt right to you, you made the right decision. If by chance you think you made a hasty decision, I know of a student who changed her mind early in the summer last year, called the Ivy school they had initially turned down and were allowed to enroll. Hope this helps.</p>
