Is a faster way to solve this $$\frac{6^3(4^3)}{(6^2)(4^2)(2^2)}$$ = $$\frac{6(4)}{(4)}$$ = 6?

Faster than breaking it down into prime factors, that is.

Hi gmatser1,

Yes, your approach is pretty fast. What is the source of this question? I ask because the GMAT would almost certainly be a bit less obvious about how to get to the solution. While you'll be tested on these basic concepts on Test Day, you'll have to do a bit more work to get to the correct answer than what you had to do here.

Thanks for the response EMPOWER. The source is Sackmann's 1800 Quant questions.

Hi gmatser1,

Have you been working with any other resources besides this book? And how have you been scoring on your practice CATs (including the Quant and Verbal Scaled Scores)?

Yes––MGMAT combined with the OG and all of the VeritasPrep videos––but I recently hit a wall in the Q33-40 range (according to Magoosh) I'm trying to get out of. I'm trying to really find my weaknesses with the Sackmann set. A big overarching problem is Data Sufficiency. I hate it!

Hi gmatser1,

How long have you been studying?

Data Sufficiency is a question type that most Test Takers have never had to deal with prior to studying for the GMAT, so it's okay to feel a little frustrated with the category. However, DS represents a big 'chunk' of Quant questions on Test Day, so you can't allow yourself to get emotional about it (much less "hate" the question type). Data Sufficiency has patterns and a logic to it that you CAN train for - there are tactics and ways to organize your work that can make the process of dealing with DS questions relatively painless. If you're not comfortable with the current approach that you're using, then you might have to change your tactics.

You mentioned being in the Q33 - Q40 'range' in Quant, but that's a rather broad range. Have you taken either of the 2 free CATs from www.mba.com? If so, then what were your scores (including the Quant and Verbal Scaled Scores)?

Hi EMPOWER. I have been studying for a little over 4 months. I have never taken a full CAT, mostly because I have recognized serious weak spots that cause Magoosh to rate me in the Q33-40 range that to me would make a CAT pointless in my opinion (if I can't get a 600-650 question right in 2 minutes without the CAT pressure, why add the CAT pressure into the mix?) Thanks so much for the advice on the DS. *Slowly* but surely it's beginning to come to me.

Hi gmatser1,

While you might not feel 'ready' to take a FULL CAT, you really MUST take one. We can acknowledge that you might not perform perfectly on that first CAT, but it's just the first one - you'll take many over the course of your studies. What we really need is a broad 'baseline assessment' of your skills - not just your AWA, IR, Quant and Verbal skills though - we need to learn about how you handle endurance/fatigue issues, what pacing problems (if any) you might have, general 'organizational' issues, etc. Those early CATs are NOT pointless - they provide valuable information that you can use to target your 'weak' areas and fix problem issues.

(24)^3/(6)^2 (4^2) (2^2) = 24*24*24/24*24*(4) = 24/4 = 6

I understand. Do you have a recommendation on which CAT I should use? I don't want to waste an Official GMAT CAT for this. Thanks!

Hi gmatser1,

We need a realistic assessment of your current skills, and the GMAC CATs are the most realistic ones available. Taking one to establish a baseline score is not a waste as long as you use the CAT correctly.
