I was wondering about V34-V38. At V34, does that mean more 600 level questions answered correctly and V38 is more 650-700 questions answered correctly? And then anywhere past the 80th percentile is 700-level questions?
I'm happy to respond.

That will indicate the overall relationship between raw score and 800 score.
As far as the difficulty of questions that the CAT is feeding you ---- first of all, that is proprietary information of GMAC. Nobody outside of them know is, and even if i did know it, if I revealed it, that would mean they would have the legal right to cart me away and shoot me in a back alley --- or something like that
I think it's safe to say that the CAT is always sweeping through several difficulty levels, some much harder than your "level", and some much easier. That's precisely how they zero in on your level --- thorough a wide variety of difficulty levels. See this blog:http://magoosh.com/gmat/2012/what-is-th ... tive-test/
Finally, do NOT interpret the difficulty levels of questions as scientifically measured values
. GMAC itself does conduct large scale statistical studies, so they legitimately could give exact score equivalents to each and every one of their questions --- but of course they NEVER release such juicy information to the public. Test prep companies, the folks who write most of the practice questions you see here, are usually guessing. For example, the difficulty ratings here on GC ---- I would estimate that 95% of those are guesses out of thin air, with absolutely no data backing them up. I know when I post a question I have just written ----- I would prefer not to assign it a difficulty, because it's often hard for me to tell (I wrote it, so it seems easy to me!) ---but the GC system forces me to assign a difficulty rating to the question whether I want to or not, so I have to guess. Yes, I have seen a lot of questions, and written a ton of GMAT practice questions, so probably my guess is a little better than that of someone who is just starting out. Nevertheless, anything that does not have the backing of a significant supply of data, I consider not much better than a guess. And, I believe, that's the situation of most of the experts who post questions on GC.
Does all this make sense?
