To those who have taken recent GRE's or have heard about those who have taken, what do you think?
I noticed that this most recent sample test is significantly more difficult than the older sample tests. This is evidenced by the percentages of test takers who got each question correct. There were many more questions on this sample test which around 30% or less got correct. Maybe too many people were getting near-perfect scores, so ETS made a more difficult test in order to better discriminate test-taker performance.
