ETS has released the 3rd edition of the Official Guide to the GRE General test. They have also released the 2nd edition of the Official GRE Quantitative Reasoning Practice Questions. Both of these guides are identical to the older guides. I continue to recommend these guides for practice and preparing for the GRE because they both contain official GRE questions. If you already possess the older guides, then there is no reason to buy these newer guides. If you are just starting out your GRE preparation, then look to see if you can find the older editions at lower prices and save some of your money.
