<p>how accurate is this site?</p>
<p>It will never be possible to say. I don’t put hardly any weight on their calculated probabilities because so much stuff an adcom considers is omitted. But I find it useful to look at the scatterplots of applicant attributes, since I don’t have access to something like Naviance. Even then, given that the data is all self reported (and there are clearly fabricated applicant profiles), one’s ability to interpret the data is conditional.</p>
<p>what site?</p>
<p>Not very, given that most of the chancers are relatively inexperienced posters who just want to be chanced back.</p>
<p>Still, if people are telling you that Harvard is almost impossible, I would seriously reconsider your college list. CC is decent at putting people within particular “brackets” of schools (eg, HYPSM), if not at chancing for individual schools.</p>
<p>I’m guessing OP is referring to
[CollegeData</a> - Prepare & Apply - Admissions Tracker](<a href=“http://www.collegedata.com/cs/admissions/admissions_tracker.jhtml]CollegeData”>Resources | CollegeData)</p>
<p>Then there is Naviance which is a subscription service that some schools subscribe to.</p>
