We're doing some research into the GMAT scoring algorithm, and specifically into how questions are calibrated (how the difficulty level of questions is determined). We understand the mathematics behind the process, but we want to collect some data about particular questions, and for that, we are hoping to find some volunteers to answer a few GMAT-style math questions. The calibration process uses your ability level, so we are only looking for volunteers who know their Quantitative scaled score (on the /60 scale) from either a recent GMATPrep test or from a real GMAT exam. We're asking people to complete a 20-question math test, so it shouldn't take longer than 40 minutes.
What will you get for participating? Well, you'll see 20 new GMAT-style math questions, and I'll send you complete solutions after you're finished the test (all for free, of course)- I'm hoping that this will help people with their GMAT preparation. And if we are able to collect enough data, and if you're interested, I'll also be able to tell you the precise difficulty level of each question ('this is a 630-level question', etc). A few of the questions are very difficult, in my opinion, so there should be something to interest people of all levels of ability. If you might be interested in helping out, please send me a personal message through this forum, and I'll send you further details.
Thanks!
Ian

Thanks Gabriel- I'd be grateful for your participation. I'm sending you a PM now.
We do need quite a few volunteers, so if anyone else is interested, please get in touch by PM. After you complete the 20-question test, I'll send you a document with solutions to the questions, and a few (hopefully useful!) tips about how to approach other GMAT questions. Thanks again to everyone who has contacted me already.

Thanks to everyone who replied above- end of a long day here, so I'll send you PMs tomorrow. We can't have too many volunteers, so if anyone else is interested, please do send me a PM.
