I have approximately 500 questions from Kaplan
's GMAT Qbank. The questions are arranged by subject (PS and DS) and level of difficulty (easy, medium, and hard.) Additionally, the sections are arranged by question type (number properties, set properties, arithmetric, algebra, inequalities, geometry, and proportions.)
I paid for the Kaplan
Qbank and they have been a big help to my studying.
I've found that after doing my initial preparation I really needed to hone in on certain areas that I was having problems with. I screen captured all the questions and have them saved.
I would be willing to share this information with others in exchange for the cost of a disk and postage. We all should go to Wharton.
Please email me @ email@example.com
for details. Thanks.
