HELP! Summer opportunities??

<p>I'm a sophomore in the midwest, I am interested in comp sci - hoping to apply to UC Berkeley or something close to that caliber. So far this summer, I am volunteering at my local art museum (for the second year) and am looking into getting a job at Barnes and Noble. I know I want to do something academic this summer also, but I don't know what yet. It is too late for many programs (CTD, etc.), and they are thousands of dollars anyway... Should I do something online? Should I consider my local community college? Should I try to develop an app? I'm sort of lost. I would greatly appreciate your input. </p>

<p>Thanks!</p>
