<p>The ranking of schools - I would not go to Parchment.</p>
<p>Preference of schools is what we are discussing. We know yield for schools and some even publish cross admit preference whereas this site will have information only for what the user input.</p>
<p>As Sam Lee mentions, if reality does not line up with the output for preference, is it a valid output from a website?</p>
<p>200,000 acceptances can sound like a lot but it is not. Most kids or parents who are savvy enough to use websites get accepted to 5 or more colleges even if they get turned down by their reaches. A school with about 800 kids might average 8000 of them and there may be only 20,000 out of a million students or more who graduated high school.</p>
<p>2-5% of students participating sounds like Harvard admit rate.</p>
