Why does the Academic Index calculator use 3 subject tests?

<p>This is just something I'm curious about. All colleges except Georgetown require two at the most. Why does the academic index calculator use your top three scores?</p>

<p>Because it is an easier comparison with the 3 subject SAT I then. The academic index calculator is kind of meaningless.</p>

<p>Yeah, I knew it was pretty meaningless. Was just wondering whether Ivies secretly used 3 subject tests when available :p</p>
