The General Part of the SAT Is Highly Correlated with the SAT

The general part of the SAT is highly correlated with the SAT achievement tests. For that reason,

A) it makes sense for colleges to require both tests for admission given all of the extra information that is provided by the second test.
B) it makes sense for colleges to require both tests for admission since one is more likely to predict school success significantly more than the other.
C) it does not make sense to require both since they likely test very different skills.
D) it does not make sense to require both since they could predict grades just as well from one score as from both.
