Summer@Ivy League University

<p>I'm interested in the summer programs some Ivy Leagues provide for High School students such as Summer@Harvard, Summer@Brown, Summer@Stanford, etc. But are they actually beneficial? Is it worth the money? If so, which do you think is the best to go to during the summer? I'm just wondering because I'm a 9th grader and I want to join a summer program at a university next summer in 2014.</p>
