I found a booklet that has official gmat questions but it's pretty old, 1992-1994 old! I also found Powerprep from ETS. I'm thinking that these questions eventhough they are official, because they are old, they should be easier than the latest ones are. So I'm thinking that if i solve them i might get better at the medium questions thus, reducing the possibility of answering a medium question wrong. Powerprep has 2 tests which are adaptive and i think it will be a good resource for questions as well. Any GMAT pros out there who can provide some perspective on this matter?
