no, for the P.S.A.T., which is the Pre-S.A.T., you dont really know what to study for. its over EVERYTHING that you have learned. and its preparing you for the real thing, the S.A.T. test. im not taking it until 10th grade, next year!! but good luck and i hope you do well!!
There is no need to study for the test because its only practice. Besides, you don't even know what to study unless you have taken it a least one time before!
