Approximately 40% of the questions you'll see on the quantitative section of the GMAT are Data Sufficiency questions.

Let that sink in for a minute.

Okay, so it's pretty obvious that if you want a high score on the math portion of the GMAT, you're going to have to master this unique and challenging question format known as **Data Sufficiency**. And let's be honest. If you're like a lot of our students, Data Sufficiency problems can be confusing -- at least in the beginning. It's such a bizarre way to think about math. Indeed, it's probably unlike any type of quantitative question you've ever seen before in your academic career.

But we have good news for you. By learning how to think about Data Sufficiency questions the right way and by adopting just a few simple methodologies for the most commonly-tested data sufficiency question patterns you'll see on test day, you can **turn these crucial question types into one of your biggest strengths.** In fact, after completing this GMAT Data Sufficiency course, you may even wish Data Sufficiency questions made up an even larger percentage of total quant problems (yes, *seriously*)!

* "In addition to teaching all the quantitative principles you will need for success, his courses also teaches you how to answer questions by using logic and non-standard techniques that are much easier to memorize and were a huge help when I was stuck during the test. I strongly recommend his course to anyone!"* -- Matt Kunzler, USA

Specifically, here's what this course covers:

- The best way to tackle each of the most commonly-tested Data Sufficiency question patterns tested on the GMAT;
- Why it's so important to pre-think the sufficiency requirements before looking at the statements, and how to do so;
- Simple elimination strategies for quickly and easily eliminating wrong answer choices after making determinations about the statements;
- How to "be the judge, not the jury" when evaluating each statement in isolation;
- A nuanced understanding of answer choice "D" and how it can help you avoid falling into a common D.S. trap;
- Why you should wait as long as possible before considering the two statements together -- and how in most cases, you may never have to!
- The #1 strategy you should employ whenever you see variables that will all but guarantee you get these common D.S. algebra questions correct;
- Why you shouldn't trust figures or diagrams (and what to do instead when you see them);
- How to answer the all-important "Yes/No" question pattern;
- Review of integers, ratios, percents, and other math concepts that are tested regularly in the context of Data Sufficiency;
- Other common question types, with lots of application examples.

- Test your understanding with our 10-question practice worksheet (available as an online quiz or downloadable PDF) of GMAT data sufficiency questions of varying difficulty levels;
- Detailed video answer explanations for each of those 10 sample problems;
- Get your questions personally answered by one of our GMAT experts via the Comments/Questions area in your member area;
- 6-month course access -- plenty of time to master this important question type and get the GMAT score you're shooting for!

Whether you're new to the GMAT and still struggling to get your mind around how Data Sufficiency questions work, or you already have a solid math foundation and you're simply looking for an edge to get those last few points so that you can get into a top-tier business school, this course is for you.
