Hello guys. I've completed my second practice test. I was using Princeton review practice. I've scored Quantitative 44, though I've made 4 mistakes (1 in experimental problem). is it possible to get such a low score for this number of incorrect answers on real test?! I know that it matters on which questions you've made mistakes (on easy ones or difficult ones), but still ?! What is the maximum number of incorrect answers to score above 49?! Can algorithm be way too conservative or is it realistic?!

There's no real way to know, specifically, whether PR's algorithm is correct. The GMAC tells test prep companies very little about its scoring algorithm - we know the basic math behind it (Google 'item response theory' if you want a taste of what's going on behind the scenes!), but very few of the actual numbers. The best you can do is to take one or more official GMAC GMATPrep practice tests and go from there - for obvious reasons, their algorithm is the most accurate, although their practice tests aren't as good in other ways (for instance, the explanations are bad to nonexistent.)

Thanks, I've purchased Navigator from Manhattan and 6 practice tests, hope it will enhance my skills, particularly in verbal secton. But overall, i think that 44 score in quant for 4 mistakes is unfair :D
