GRE - Why is the raw score out of 50 points??

[hannahmichelle]

I took a review test from the Princeton Review Cracking the GRE, and when I was computing my raw score (i.e. counting how many questions I got correct), I noticed that the highest raw scores for Math and Verbal were in the 50s, even though there are only 40 questions for the V and 40 for the M. Why is that? I got 34 questions right out of 40, not out of 50...

I would suggest downloading the powerprep software from ETS. The Powerprep tests give you a real score at the end (from 130-170) and my practice test scores were basically right on with my actual tests scores.
