What to do during graduated Summer?

<p>I graduate from high school this year, and will hopefully end up at UM-Ross or NYU-Stern.</p>

<p>Is there anything I can do, or should be doing, over the Summer that will make a significant impact on my resume?</p>

<p>The past two summers I've worked >1000 hours doing research at a local institution. Freshman summer I was a CIT at my local Club Fit.</p>

<p>Regards in advance,</p>
