Or, alternatively, you could just skip over "general intelligence" and get to your second measure that's directly validated against college outcomes – SAT score.

(My understanding is that the "general" GRE – not the math subject test – is less of a predictor of completing a PhD, but I think we can come up with a hundred reasons why.)
