If you meet their samples then you should go for it. If they've already decided that those are the metrics they want to use then that's what matters for their data gathering purposes.

Also, if you have GRE and SAT scores in that range, while it is possible that they aren't really a reflection of intelligence in the 99.9th percentile (ignoring for now what intelligence means in any useful sense) one is almost certainly well above the 95th percentile.
