That cost-benefit analysis makes no sense if you had a pretty good scores. What's the point in fudging a few extra points if it means that diligence reveals you to be a liar?

It would also be somewhat suspicious if you went to a so-so college but allegedly had a perfect SAT. It would only make sense to lie if your score was well under 1600, you went to a college that makes sense for someone with a perfect SAT, and you didn't think it was likely they would follow up with a request for the official score report.

In service to the point, if you're _really_ smart—like definitely going to grad school smart—you apply to universities with the best faculty for your intended area of study. Often that is a sole professor at a university you've never heard of, but the researchers in that area of study regard as a top school.
