<p>You can't take these rankings too seriously. A school that's listed #5 could easily be #25 in reality. I look at PR reviews for kicks mostly.</p>
<p>Also, about the survey... maybe they don't ask students how hard they study, but they ask specific questions such as how many hours on average they study per week? Hopefully they don't just give the student a 1 to 5 scale and have them pick. </p>
<p>In general I do agree with the 2007 rankings; the key schools are all there: MIT, Caltech, HMC, Cooper Union, the military academies, CMU, etc.</p>
