Dear GMAT Test-Taker,
Thank you for your interest in graduate management education. Taking the GMAT® exam lets schools
know that you're serious about your educational goals. By using the Official Guide to prepare for the
GMAT exam, you're taking a very important step toward achieving your goals and pursuing admission
to the MBA or business master's program that is the best fit for you.
This book, GMAT® Official Guide Quantitative Review 2019, is designed to help you prepare for and
build confidence to do your best on the GMAT exam. It's the only guide of its kind on the market that
includes real GMAT exam questions published by the Graduate Management Admission Council
(GMAC), the makers of the exam.
In 1954, leading business schools joined together to launch a standardized way of assessing candidates
for business school programs. For 65 years, the GMAT exam has helped people demonstrate their
command of the skills needed for success in the classroom. Schools use and trust the GMAT exam as
part of their admissions process because it's a proven predictor of classroom success and your ability to
excel in your chosen program.
Today more than 7,000 graduate programs around the world use the GMAT exam to establish their
MBA, graduate-level management degrees and specialized business master's programs as hallmarks of
excellence. Nine out of 10 new MBA enrollments globally are made using a GMAT score.*
We are driven to keep improving the GMAT exam as well as to help you find and gain admission to the
best school or program for you. We're committed to ensuring that no talent goes undiscovered and that
more people around the world can pursue opportunities in graduate management education.
I applaud your commitment to educational success, and I know that this book and the other GMAT
Official Prep materials available at will give you the confidence to achieve your personal best
on the GMAT exam and launch or reinvigorate a rewarding career.
I wish you success on all your educational and professional endeavors in the future.
Sincerely,
Sangeet Chowfl.a
