Thanks for the information.
Actually I have prepared for GMAT earlier & got 570. The main reason was lack of practise of quantatative questions.
I have gone through MGMAT guides
, they are good for preparing fundamentals.But they dont have practise questions. I heard about Complete GMAT Math by Jeff Sackman
, but dont know much about it. If anyone of you used this book, pls share u r views.
