Has anyone used the BTG practice questions? If you have, what is your experience/opinion of the questions?
I have used them. The questions I saw were generally great. They were all relevant, thoughtful, on target, and would be a great proxy for the GMAT.
Some of the questions are direct modifications of OG questions which is a pro and con. For example, compare "Average of a and b" with OG12-PS84. On the one hand, the questions serve as a terrific proxy for OG questions. On the other hand, some of the questions will basically be repeats. It's a double edged sword. Creating realistic, new OG problems is almost imposible, so you'll always be playing a trade-off between relevance and novelty. This q-bank leans towards relevance.
I LOVE the filters that you can turn on and off with a click. It's very Kayak-like.
I'm sure in the future they're planning to add some deeper analytics to help you hone in on your weaknesses. As it stand right now, it's a solid Q-bank.
