Ten months ago we introduced the Veritas Prep GMAT Question Bank, giving every GMAT student around the world completely free access to hundreds of realistic GMAT questions of all types. Today, we celebrate an incredible milestone: more than one million GMAT questions served!
Over the past ten months we have tweaked the GMAT Question Bank, made countless performance improvements, built in more diagnostic feedback for students, and added even more GMAT questions. We remember being giddy when, over the first weekend, we crossed over the 1,000 mark in terms of questions served. Now that’s no big deal at all as the GMAT Question Bank continues to grow in popularity month over month.
Most importantly, all of the data that we have collected from those one million responses has gone into building our entirely new computer-adaptive GMAT practice tests, which were built using the same philosophy (Item Response Theory) that is behind the Official GMAT. Those are the same tests that our GMAT prep students use, and you can try one of them for free if you haven’t already.
This is how we explained it last October:
So what’s the deal? We’ve created this tool and opened it up to everyone so that we can collect loads of data on our questions. We’ll use the data we collect to measure and refine our questions, which will then go into new generations of our GMAT practice tests. In effect, by answering these questions, you’re helping our system learn about the questions — which ones are easy, which ones are hard, which ones are confusing and need to be refined, etc. The system is also learning about each user (this is one reason why the system asks you to create an account and log in)… It’s an iterative process that helps it measure users by seeing how they did on certain questions, and it assesses those questions by seeing how well certain users performed on those questions.
Where to from here? We’ll keep adding more sample GMAT questions and building in new enhancements. We’ll continue to use the data that we collect in the GMAT Question Bank will continue to make our computer-adaptive practice tests even more accurate. And, we will keep the GMAT Question Bank free for everyone to use. It’s too good not to share with the world!
