I took the GMAT on Feb 18th and am planning on taking it again soon. I got a 660 (66% math, 89% verbal) and have been running through the offical guide and was wondering about how the difficulty works. Does it go from easy to hard? I have been doing 22 problem solving and 15 data sufficieny at a time and am now on question 132 for problem solving and 90 for data sufficiency. So far I have only run into 1 or 2 questions that I answered incorrectly (and about 10 that I struggled with more than I would like). The shortest a group of 37 questions has taken me has been 45 min, and the longest has been an hour.
It seems like the questions in the last 2 groups have gotten a little harder than the eariler ones. Am I doing medium questions now? When will I see questions that are indicative of the hardest questions I'm likely to see on the real exam? I guess when I took the real test I didn't do very well because I always felt like I was answering the questions correctly. I guess I fell for a few of their traps.
For most 700+ scorers, I can say that the only the last 20-30 questions come close to the actual GMAT. You will see some real tough problems to solve in 2 mins.
I will recommend that you participate in the forum here. Just go through the previous posts and discuss the tougher ones. If you do this diligently, i cant see any reason why you cant do better.
