CSS Profile for Early Action

<p>Hello!</p>

<p>I'm currently filling out the CSS Profile as an early action applicant for the University of Chicago which requires it to be submitted by November 1st. </p>

<p>In one of the sections, Parents' 2012 Income & Benefits (PI), should I simply make estimates for all the fields based on my parents' 2011 return? It's just a bit confusing at the moment. Thank you!</p>

<p>That and any adjustment to pay (raises) that your parents know of.</p>
