I took a past CS gre just to see how I would do and got an 840/900 without any type of prep, and I was considering taking the math GRE anyway to win a bet. Does anyone know if either of these would look good on a physics grad school application?
If your planning on physics grad school you should take the Physics subject test, not CS or Math. There is a reason they have a separate subject test for physics. Don't assume grad schools will let you substitute another subject test for the PGRE, because they probably won't.
