This is from a Consulting McK & Co. case: How can you do this math quickly: solve for Y in millions (M). (You have 2 minutes) (85% * y) * 1% = 180M [(40% * 1% * y * 85%) + (.4% * y*85%) ] Please explain in detail the two minute shortcut!!! Gracious!!!

i was little stunned too. but it was mostly ego. i might retake it in November, but not until then

the first time I did them I missed b/w 4-9. I retook them two months later and missed between 0-3.

JJAY - Manhattan's math is not very representative of the real test, but that being said if you can score a 50 or higher on Manhattan, then you'll score at least 48 on the test. Manhattan's math while not representative is really time-confusing and features layered concepts. But if you have the ability to score a 50 on these tests under time conditions, GMAT math should be more a less a cinch. I was lucky to score a 47 in Manhattan and this is reflective on my actual test. Manhattan's verbal is nothing like the real thing. The SETS is all I have to say.

buddy I scored a 45 on quant. So I am not the person you want to get quant advice from. But for the record, the math sets are not representative.

I wish. I don't know what happened. But it's out of my hands now. As far as verbal sets go, must of my problems came from incorrect answers on the Sets. The others were really tough S.C. and I found the answers on Testmagic. One thing is for sure, the bold face on the Sets blow the actual gmat bold faces out of the water. I actually did the sets twice and always under timed conditions. Do the sets twice, and learn from the mistakes and I guarantee you will score at least a 42.

I think math was 78th percentile:( I have no idea what happened...but OMG right before the math was about to start I bumped into the monitor and the screen went dark. I thought I was so screwed, but luckily they got the monitor up and running before the 60 second tutorial expired!!! And yes the sets are critical. Compared to the sets, GMAT reading comprehension is a joke.

First off, thanks to the homies: ravindra (the o.g. assassin), jjay (for the motivating words), mfeaspire (for the awesome math techniques),vrider(my score twin - although you have a much better split) apple77 (for just being cool and predicting my score perfectly), hjafferi (you're gonna score a 750+), vnf(she's surgical with her math skills, and anyone else i forgot. Debrief: Profile: African American Male/Liberal Arts Major/Strategic Planning I don't want to be too long winded. Material I used for prep: Scores: Manhattan Prep 1 - 710 Manhattan II - 700 Manhattan 3 - 650 (I don't know what happened here) Manhattan 4- 710 Manhattan 5 -710 Powerprep - 740 Powerprep 750 Official GMAT for Review All the Manhattan Books (Although verbal is useless and the sentence correction book is truly overhyped...at least for native english speakers) Kaplan Math and Verbal Review Books (Excellent in my humble opinion) And the verbal sets!!!!! I cannot stress the importance of the verbal sets. I have always been particularly strong in verbal (42 and above), but imagine my suprise when I saw 4 questions straight from the sets on my test. I ended up finishing with about 20 minutes to spare. Anyway, the math is really straightforward and it is the exact same level as GMAT Prep. I was always scoring 51 on GMAT Prep but that was skewed as a I answered many of the questions on this forum. I think I really blew it on the actual test b/c I had improper time management. I believe a 47-48 is more my level. I want to retake, but my apps are due in 6 weeks so for now I just have to make due. That's pretty much it I guess, if you have any questions let me know. One piece of advice for all you newbies to testmagic: answer as many questions as possible, and no more of this IMO A or B, crap. We're supposed to be exchanging techniques not trying to build our status from "trying to make mom and dad proud" to GURU Anyway, that's my spill. You guys will definitely see much less of me on this forum, but it's been great. Feel free to ask me any questions.

Something went horribly wrong in math:rolleyes:!!!! Time to drink. I need to consider a retake, but not before first round apps are due...:mad:

good stuff, bud

Have you considered a tutor. Also, you might want to practice the sets.

hey, bud i like that approach of subtracting 1. it's less time consuming/more efficient. good stuff

Hey, bud. For purposes of GMAT, 0 is always considered even. But even if we chose not to use 0: A is still insufficient. For example: If N = 6, the (6-1)(6+1) = 5*7=35 which is not divisible by 3. Let me know if you're still confused.

Anything above 4 is good. It's true.

If 5^x - 5^(x-3) = (124)(5^y) If 5^x - 5^(x-3) = (124)(5^y), what is y in terms of x? a) x b) x-6 c) x-3 d) 2x+3 e) 2x+6 Hey bud, 5^x - 5^(x-3) is the same as A - AC. You can factor of the A, and you get A(1-C). So with our equation you can factor out 5^x. 5^x - 5^(x-3) = 5^x- 5^x(5^-3) = 5^x(1 - (1 *(5^-3)) = 5^x(1-1/125) = 5^x(124/125) So, 5^x(124/125) = 5^y(124) 5^x = 5^y(124) * (125/124) 5^x =5^y(125) or 5^x= (5^y)5^3 So, 5^x =5^(y+3) or x = y +3. So, y = x-3.
