GMAT Data Sufficiency Challenge Questions

January 17, 2007

One 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.

Beginning today, I am releasing a set of 100 test-like GMAT practice questions approximately once per week. Each set will focus on a specific area and/or difficulty level. This way, you won't waste your time doing questions you don't need to. Most of all, you'll stay focused on precisely what you need to learn to ace the GMAT.

Data Sufficiency: Challenge

The first document in this series contains 100 difficult Data Sufficiency questions that you can't find anywhere else. The problems cover nearly every subject that can arise on the GMAT:

• Algebra
• Geometry
• Number Theory
• Word Problems

In addition to these 100 questions, the document also includes:

• Lists of included questions indexed by content area
• 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 Data Sufficiency: Challenge problem set is available for only $24.95. Buy it now, and a PDF file will be delivered to your inbox within 24 hours.
