upasanadatta, I noticed you rated the gmat question pack 1 a 10. How did the "hard" quant questions fair with the questions that you faced on the actual gmat? How about verbal as well? Going through many of the "hard" quant questions, I definitely found many of them difficult when I tried to simulate the quant section in exam mode (37 questions - mostly med and hard difficult questions). I found them more challenging than the OG and GMATPREP quant problems.
Hi
I also did the same thing-set of 37 questions medium+hard timed....my accuracy used to be around 75-80%...with more than 50% HARD quant question wrong. Yes, I also found them much more difficult than OG or GMAT Prep or the real GMAT....infact my real GMAT was so easy that I was afraid I had screwed up rather badly. Apart from a few questions with weird looking geometrical figures-i am guessing they were experimental question-the test aligned pretty closely to GMATPrep tests....I even ended up getting the same score as my last GMATPrep test....
While I found the prep pack to be great practice, i wouldn't read too much into its difficulty level. All the best!
