Number Properties: Challenge
March 16, 2007One of the most frustrating things about GMAT preparation is the difficulty of finding adequate practice materials. There’s plenty of stuff out there, but most of it is bad. Beyond the questions in The GMAT Official Guide and The GMAT Quantitative Review, the pickings are slim.
No longer.
Number Properties: Challenge
This document in this series contains 100 difficult Number Properties questions--48 Problem Solving, 52 Data Sufficiency--that you can’t find anywhere else. The problems cover nearly every Number Properties subject that can arise on the GMAT:
- Factors
- Multiples
- Prime Numbers
- Exponents
In addition to these 100 questions, the document also includes:
- Lists of included question indexed by difficulty level
- An answer key for quick reference
- Complete explanations for each of the 100 questions
Quite simply, these are the best practice questions on the market. They are carefully patterned after published material: different enough that you’ll reinforce the skills you need for the test, but similar enough that you won’t spend time learning concepts that won’t apply to the GMAT.
Right now, the Number Properties: Challenge problem set is available for only $24.95. Buy it now by clicking the Google Checkout button, and a PDF file will be delivered to your inbox within 24 hours.
