Advanced GMAT Quant from Manhattan GMAT

This will be a good subject to get some other points of view.

I am sure there are people on both camps who swear by their experiences. There is one school of thought that says that if you practice on really hard stuff -- then you will ace the easy stuff. I am not so sure about this though. If you practice on really hard stuff -- you might miss the subtlety and minor twists in relatively easier questions (something GMAC does).

It's important to get the easy / medium questions right and make sure you avoid silly mistakes -- this will ensure that you maximize your score. I'm sure there are others who feel differently about this strategy than I do.

For example, I see a number of people on this forum practice LSAT CR and RC questions. I know a bit about the LSAT and although I took it 10 years ago not much has changed on the exam. And most of the guys doing the LSAT CR questions aren't the ones scoring V46 and V48 -- trying to get V51. A lot of the guys doing the LSAT CR and RC questions are the ones scoring V31 and V32 -- hoping that practicing the *tough* stuff from the LSAT is going to improve their score. I would do the exact opposite -- work on fundamentals -- such as finding the conclusion of the argument and understanding the underlying logic -- improving critical reading skills etc.
