Mathematics GRE

Hi Guys,
can anyone tell me how to score this test, i.e. to convert my raw score into a 'scaled score' and a percentile??
If not, any idea how good a raw score of 42.75 (46 correct, 13 incorrect, 6 blanks) is? I mean, roughly, is this 70-80 pc or 30-40 pc, or something in between??

Thanks a lot!!

the princeton review practice test doesn't really resemble the actual exam.

There isn't a scaled score because there are no average results on the test. If pressed, however, just use the scaled scores on the released tests and average them.
