Yes, QP1 is now known as GMAT Official Practice Questions. Why? No clue. Maybe more people are searching google for GMAT Official Practice Questions than Question Pack 1. Anyways, GMAT Official Practice Questions or Question Pack 1 or whatever the hell it's called is still a great buy. We have a full question pack 1 review here with some suggestions for how to use it in your GMAT preparation. You can buy GOPQ here. Beware it's online only so you need an internet connection to access it. And, unfortunately, you're only renting it for 12 months. So go ahead and wait to buy until you're actually going to use it. Here's a little blurb we wrote on the new online GMAT Prep Software updated for the new shorter GMAT.
