What to do the summer before senior year?

<p>Apart from thinking about colleges and working on the Common App essay, what are other things that would help to do in the summer before senior year rather than during the school year? When do supplements become available?</p>

<p>Prep for SAT’s if you are taking them again and I usually learn the first month or so of my AP class course work ^^
oh and I’m going to India this summer <em>woot</em> :D</p>

<p>Climb Mt. Everest.</p>
