7 - 760+: Acknowledge That “Your Way” is NOT Necessarily the Fastest Way (and Then CHANGE Your Approach)

The GMAT is a remarkably consistent and predictable Exam, so improving your performance isn’t just about ‘fixing’ the things that you are doing ‘wrong’ – it’s also in developing the proper skills to improve on work that you can already do.
Consider the following question. For many “math thinkers”, the approach would be “system algebra” – write out the appropriate equations and then solve for whatever the question asks for. That approach will absolutely get you to the correct answer here – and I suggest that you try it. Make sure to time yourself though - we need to know how long it would take you to solve this question using an algebraic approach.
Andrew has a certain number of coins in his pocket. He has three times as many dimes as quarters and six times as many nickels as dimes. A nick is worth $0.05, a dime is worth $0.10 and a quarter is worth $0.25. If he has a total of $10.15, then which of the following represents the number of dimes in Andrew’s pocket?
How long did it take you? For most GMATers, this question would require 2-3 minutes of work. If you’re really great at algebra, it might take you less time than that.
Now, I bet that I can show you a MUCH faster way to get to the correct answer – and it’s an approach that you’ll be able to use 2-3 times on the Official GMAT. Tomorrow, I’ll show you how it works and how to use it.
GMAT assassins aren’t born, they’re made,
