It’s the last Friday in March, and all good things must come to an end, including Hip Hop Month in the GMAT Tip of the Week space. But if you’ve been reading along with us all month, hopefully your iPod or car stereo has become your best study partner. While you’re driving home from work and the Kanye/Good Music track “Clique” comes on, you might hear Jay Z’s verse and immediately start thinking about sequence problems:
Turn that 62* to 125, 125 to a 250
250 to a half a million, ain’t nothin’ nobody can do with me
(*clearly this is a sequence that doubles every term, so Jay’s leaving out the .5 for artistic reasons)
While you’re driving and singing along, you’re probably thinking “and the next term is a million, then two, then four, then eight”, and you may even be fixating on that line “ain’t nothing nobody can do with me” the way that GMAT item writers are. What can they do with it? They can ask a question like:
In Jay Z’s sequence, where a(1) is 62.5 and all terms a(n) are equal to a(n-1) * 2, by what percent is term a(10) greater than a(8)?
And they’d make it hard because you’d say “of course you just double a(8) to get to a(9) and then double it again to get to a(10), so it’s 4 times difference, so 400%”, when really it’s a 300% increase. (4 is 300% greater than 1 – the key is that the question is not asking “what percent OF” but rather “what percent GREATER THAN”.
…which is all just a long way of saying that as you look around they don’t do it like your GMAT study clique, a group of musicians (and friends here at Veritas Prep) to help you gear your mind toward the GMAT through song. Your study clique includes:
Notorious B.I.G., who can teach you valuable lessons about inequality problems on the GMAT.
2Pac, who sees through the most common Data Sufficiency trap answer.
Ice Cube, who wants to make sure test day is a good day for you.
Vanilla Ice, who appreciates subtlety in Sentence Correction.
Macklemore, who shows you how to be thrifty with Data Sufficiency statements.
As you study for the GMAT, you have a big team behind you and opportunities to sharpen your mind. Ain’t nobody fresher than your GMAT study clique…until you add your colleagues from your new b-school to your Linked In clique, of course.
