<p>^ This 2-year old list is 40% weighted to whether or not an enrolled freshman is in top 10% of HS class. Considering how few applicants report class rank to elite schools, and the inconsistency with which this data seems to be reported (even the OP did not fully believe this data) on the CDS, IMO it would difficult to understand why this number should be weighted so heavily, if at all. And I am not convinced that anyone familiar with these schools would rate Washington University St. Louis as a more challenging admit than UPenn, Duke, Brown, Dartmouth, and Stanford. Or that UChicago would be considered a less challenging admit than many of the schools above it, or the many other inconsistencies with admission rates and mid-point SAT scores on this list. Personally, I don’t believe this list is particularly insightful in regards to selectivity. But, of course, your mileage may vary and everyone is entitled to their own opinion.</p>
