A lot of people feel our quant can be harder than the real thing, but people also sometimes feel GMATPrep can be easier than the real thing - so just be careful there. Your score may be somewhere in the middle.
Also, people generally find out test harder when they're struggling with one of two things:
(1) timing
(2) computation on PS
If you're struggling with either (especially the first one!), let me know.
In fact, I'll just preemptively say read this, since everyone can get better at timing and mindset:

http://www.manhattangmat.com/blog/index ... nt-part-1/In terms of what to study, yes, quant is lower for you, so agreed that your focus should be there. Focus on the low-hanging fruit categories first:
(1) places where you tend to make careless mistakes (including any fast-and-wrong problems that you weren't choosing to get wrong fast on purpose)
(2) problems you get right but take somewhat too long to do (+30-60 seconds over the expected average for that problem type)
(3) problems you miss in normal time in areas that are normally medium to strong for you
For problems you're getting wrong slowly... start getting them wrong faster. :) Spend that time somewhere else (eg, in categories 1 and 3 above).
If you'd like more specific advice on content, you can use the below to analyze your most recent MGMAT CAT (this should take you a minimum of 1 hour):

Then come back here and tell us; we'll tell you whether we agree and advise you further. (Note: do share an analysis with us, not just the raw data. Part of getting better is developing your ability to analyze your results - figure out what they mean and what you think you should do about them!)
