Thanks DanaJ. My question is more like this: you and I both take the GMAT yesterday and we both get 50Q. I figure it is possible that you did slightly better than I did (i.e. you got one fewer question wrong, or something else with the result that we have the same raw score but if percentiles were i...

Interpreting percentiles
Apologies for double post, as I realized this is not a purely math topic, although I posted only in the math section. After the GMAT, when they provide you a raw score and a percentile, how should that interpreted? Say, Q50 and 92% percentile. Does that mean that everyone who gets a Q50 sees a 92% p...

Percentile in math
After the GMAT, when they provide you a raw score and a percentile, how should that interpreted? Say, Q50 and 92% percentile. Does that mean that everyone who gets a Q50 sees a 92%, or do some people with a 50 actually see 93% or 90%? If the answer is that everyone sees the exact same percentile, th...

Sending GMAT score but not applying
Is there any negative consequence to taking the GMAT, sending the score to schools A and B, but then not applying to schools A and B? I'm still not clear on whether I will be applying for 2010 (I know, it's getting late..) but I will be taking the GMAT soon and am currently planning on sending the s...

Re: Help with questions regarding factors/divisors
If n is a positive integer, is n^3 - n divisble by 4? a) n=2k+1, where k is an integer b) n^2 +n is divisible by 6 I almost always get questions like this wrong! I generally do well on the math section but this is one thing that I just don't get the hang of. What should I do? Any excellent resource...

Re: Help with questions regarding factors/divisors
shanrizvi, I'm sorry I can't give you an answer here, but I wanted to post to second your statement. These problems also give me fits and would love to learn about how to approach these. Any resources (maybe MGMAT's number properties book?) that can help us tackle this would be greatly appreciated.

yes you are right. 4 doesnt work when put back in the original equation. 1 and 2 are the only possible solutions. which book was the question from? Total GMAT Math. I do want to caveat that this book has been great otherwise. So is the method of assuming an absolute value term is positive and then ...

is it 8? (x^2) - 4x + 6 = 3 - |x-1| =>(x^2) - 4x + 6-3=-|x-1| =>x^2 -4x+3=-|x-1| =>(x-1)(x-3)=-|x-1| squaring both sides (x-1)^2 (x-3)^2=(x-1)^2 =>(x-1)^2*[(x-3)^2-1]=0 =>(x-1)^2*[x^2+9-6x-1]=0 =>(x-1)^2*(x-4)(x-2)=0 =>x=1 or x=4 or x=2 product of all possible solutions: 1*4*2=8 Hmm..that is what t...

Algebra and absolute value question I'm stuck on
What is the product of all the solutions of (x^2) - 4x + 6 = 3 - |x-1| ?
This is a question from Total GMAT. The answer I've come up with is not an available solution. I see the explanation in the back but I think I'm missing something here. Any help would be much appreciated.

Would it also be possible to think of the shape as a cylinder plus cone? That is, you have a regular cylinder in the center, and when you take that out, you are left with a cone that effectively has a hole bored through the middle and expanded. It makes sense conceptually to me but I cannot get them...

Volume of "cone" with flat top
How would you guys calculate the volume of a cone, but with part of the top cut off flatly? I thought of 2 ways although they aren't tying out with each other, so I may be missing something.

Recommended GMAT math book for someone decent/strong at math
I've historically done well on quantitative subjects and currently work in a quantitative field (although I don't teach 10th grade math so the overlap with GMAT topics is unfortunately minimal). Could anyone recommend a prep book that reviews all math topics on the GMAT without suffocating detail (i...
