GMAT mastery through focused learning

The key to performing well on the GMAT is recognizing that simply knowing all the rules and properties is just one small step in your preparation. The bigger, more important, step is understanding and anticipating the many different ways the GMAT can test those rules and properties.

For example, the GMAT requires you to know the following about right triangles: 

These concepts are easy enough, but how will the GMAT test your knowledge of them? For example, on test day, could you get a question like the one below? 

Well, unless your test is going horribly wrong, you won’t see a straightforward question like this on test day.

Instead, you could get a question like this: 


Or this:


Or this:

(The answers can be found at the bottom this page)

As you can imagine, there's no end to the number of ways the test-makers can take straightforward concepts and twist them into unique (and sometimes devious) questions.

Given the wide range of ways the GMAT can test each concept, how can you best prepare?

The key is through focused learning, and this video course is specifically designed for this approach. Each lesson in the course covers a small number of concepts. Beneath the lesson, you'll find tons of linked practice questions (official and unofficial) that test only those concepts covered in the lesson


This approach reinforces the concepts you just learned and familiarizes you with the different ways those concepts can be tested. So, students who have been out of school for a while can efficiently master one subtopic at a time, and students seeking top scores will better understand the nuances and intricacies of each concept, so they'll have the conceptual flexibility needed to tackle unconventional questions on test day. There’s even a comment board for each subtopic, where Brent, the course creator, will answer your questions.

Each lesson in the course builds on the lesson before it. So, once you’ve mastered Right Triangles, you’re ready for the next topic, Special Right Triangles, followed by Similar Triangles, Quadrilaterals and so on.

Compare this focused approach to the more common approach of learning all the rules and properties under a broad topic (e.g., Geometry), and then answering unrelated practice questions (e.g., a circle question, then a trapezoid question, then a cylinder question, etc.). With this broad-based approach, students have fewer opportunities to reinforce specific concepts, and it’s harder to identify the similarities and differences among related questions that test the same concept. 

With a focused approach, everything you need to know about a certain subtopic is conveniently located on one page. This promotes deeper understanding and students struggling with certain subtopics (e.g., Standard Deviation) can return to that page and strengthen their understanding.
