Affordable/ best summer pre college programs?

<p>Im looking into a summer program that is affordable and that I can go to for 3 weeks in the northeastern region. Is it weird/ do you feel out of place living with people you dont know for 3 weeks? What do you do with your free time? do you have free time or is it like regular school? Id prefer one of the ivy league programs.</p>

<p>Your best bet are the free programs like RSI and TASP. Colleges would way rather see them on your resume than a paid for summer at Harvard or Brown, neither of which is inexpensive.</p>
