<p>I wouldn’t take the princetonreview results to be very reliable. Some of the rating is based on self-reporting from students. Neither the data from self-reporting, nor the sampling (which is voluntary), add up to good research.</p>
<p>BUT, I do think princetonreview is useful for making very broad cuts. A school with a 99 rating is likely to be more rigorous than a school with an 89 rating, for instance. The difference between a 99 and 95, though, is probably an illusion.</p>
