Ask the Test Maker

Dear GMAC,

I have practiced the IR section of the Official Guide, and I solved the problems very well. Now, I am praticing the IR problems of the question bank of the GMAT Prep, including the question bank you sell on line, and I perceive them much more difficult! :s . For example, there are some graphics that I have never used in my life.

The difference in the dificulty level between both sources is big.

Should I worry about that?, Is the difficulty level in the real exam like the Official Guide, or like the GMAT Prep questions bank?

Is the 0G13 enough to get a good grade (7-8) in IR?, or should I invest more time in the GMAT Prep question bank?

Thanks!

Thanks for the questions! As for your first question, all IR questions in OG and GMATPrep were selected to offer similar levels of difficulty. There is no difference in overall difficulty level between the two prep resources, and either one should give you a good idea of what to expect in the exam.

As for your second question, there is no one study method that will work for anyone. It is best to do as many practice questions as you can, so I would suggest you use both guides, and any other resources you feel are useful to you, when preparing for the exam.

Good luck!

Rebecca
