I can't uderstand one thing. I have OG 10 and OG 11 for math and I can solve almost every problem without problem but when I take a test using software math seems to be much harder and I get many questions wrong. I just don't get it? Is OG easier?

What would be an alternative source of materials to use? Princeton review?

Thanks,

There is always a difference between pen & paper and computer format.
It seems you are more versed with pen & paper format...actually its not a problem with ur basics and solving ability.
you just want to solve fast on computer and do a lot of mistake..So I would recommend give more and more test on computer under fixed time...in few days u will start getting less mistakes..
Also keep posting solutions etc in forum .this way u learn how to solve by just seeing on screena and using very less pen and paper...I hope u got my point...

i think this is an issue of there being more easier problems in the OG than what you experience on the exam. If you can solve all of the "easier" problems, then when you take the exam, you're being given harder questions. when studying make sure you focus on those harder questions more often

OG math is quite easy as compared to the real GMAT math

i'd suggest u try solving kaplan 800 math book. its a good book . must say .

Also start using ebooks than hard copies. that really trains u to the real gmat environment..

Hope this helps

Yeah harder problem will surely boost ur confidence...when u have plethora of time....u must always try to solve some harder problems, then u will never be stuck up in easier problems... ...
As suggested by others here..kaplan 800 math book is getting a good response for preparation .. so u can carry on with it if u have a good amount of time...
