Help, I don't know if I screwed up

<p>Okay, so here’s the situation. My brother is in college but he will be done in Dec 2010. My sister is going to college in January 2010.</p>

<p>When the CSS Profile asked for the number of kids in college from academic year 2010-2011, I took this to mean from Sep 2010 to April 2011. So I put down 3 kids will be in college (including me). But then I realised, won’t the college want proof before I matriculate? My sister won’t be in college till next year January, so I wouldn’t be able to get an enrolment slip from her until then.</p>

<p>Did I make a mistake? Should I contact colleges and change this information??</p>
