Can you use a calculator on the GMAT? Any tips for preparing for the exam? I am scheduled to take the GMAT in May 2012. Any special websites that you have utilized for studying questions.
If you're not adverse to spending $40 I recommend 800score.com. I used them back when I was about to take the GMAT and I found the 5 computer-adaptive tests helpful. I wouldn't use it as a pure study tool but it could be good to take 2 tests up front, see where you need to study, do additional work and then take the other 3 tests closer to the exam date.
You can find tons of information about GMAT on Google. I would prefer downloading a torrent which comprises of many useful informative books & guides which helped me in SAT.
