Question regarding GMAT study materials

[batman08]

Hi all,

I am preparing for GMAT and have the Official Guide for GMAT Review 13th Edition and Manhattan's SC book.
Can someone please tell me if should purchase the GMATPrep Exam Pack 1 and GMATPrep Question Pack 1 from mba.com as well ?
Is there any overlap between the questions in the above mentioned resources and the questions in Official Review Guide ?

Thanks!

There is no overlap, no. These can be very good additional sources of questions and practice tests - it just depends on whether you think you need the additional practice. I would start with what you have (OG plus the 2 free practice tests) and you can add in the other resources later if you feel that you need more practice.
