Do you know your true GMAT Quant Ability?

See if you can pass this GMAT Quant "pop quiz"...if you want to get a high GMAT score, then you must answer correctly:

If a, b, and n are positive numbers such that \((\frac{a}{a+b})(10)+(\frac{b}{a+b})(20)=n\) and a<b, which of the following could be the value of n?

A) 10

B) 12

C) 15

D) 18

E) 30

Think you know the right answer? To be honest, a lot of GMAT students get this one wrong (or don't even know how to start). Only those that are at the top of their level can answer this question in less than 1 minute, and without writing much at all.

I remember this question from when I started to teach GMAT Quant over 7 years ago. I was the one who took more than 10 minutes and wrote at least a page full of algebra.

Now? it's a pretty obvious question once you learn to dominate the correct properties.

Ready for the answer?

The answer is D) 18.

Did you answer correctly?

Now, here's WHY that's the right answer:

You can combine the equation like this:

\(\frac{10(a)+20(b)}{a+b}=n\)

This has the exact form of a weighted average question. The weights are a and b. The value of n goes from 10 to 20, depending on who has more weight, a or b. If a=b, then n=15 (right in the middle). Since the problem tells you that a<b, then the value of n is closer to 20, so 15<n<20. The only possible answer is 18.

Do you see how knowing the right properties and formulas can mean the difference between not having enough time to answer the last 5 questions in the exam, and being able to confidently answer seemingly hard questions, even with time to spare?

Introducing the GMAT Quant Ability Test

Many students who come to me for GMAT Quant preparation have already prepared before, on their own or with another course. It's difficult to put into words exactly what they need to change in their approach by just knowing their latest scores.

That is why I have developed this Quant Ability Test, so they can measure themselves with 43 carefully selected GMAT questions that cover a range of abilities, and then learn how a true Quant level 51 student should answer. Through the video solutions to each question, they learn different approaches that may be very different from what they are used to (possibly the exact reason why they may feel stuck).

Now you can take advantage of this tool and discover what your true level is. If you are feeling frustrated, stuck, or you think you have learned it all already but you are still not getting the high score you deserve, then take this test and you will see exactly what you are missing in order to get to the next level.

Why the value of this test is at least $150

I have administered this test manually to dozens of students in the past years, and in order to deeply understand how the student is currently thinking and explain what the correct approach should be, it usually takes at least 3 hours of class to cover every detail. At the current rate of $50 per hour, students invest at least $150 to get the insights you are about to get right now.

Because I can deliver this test online and you can do it at your own pace, I am able to offer it to you for a fraction of the cost.

$150  just $27

I'm also giving you a special bonus!
