Finished my gmat today for the second time and am pleased with the score. I significantly improved on math this time around. Basically I was not ready for the math section last time and went over many tough questions, like the ones on this site, to prepare. I feel like the question difficulty level rapidly built up from 1 to 10 and then backed off a little bit. The test contained a bunch of easy probability qs, but some nasty geometry and function qs. I actually went down in verbal by 1 point, probably because I let my reading comp get a little rusty over the past few months. The reading comps really dragged, I found them long and difficult. I should have practiced a littel more reading off the computer, because it feels different to me than reading off paper. Whatever though, I'm done. This forum has been helpful, thanks

Does anyone have a methodical approach to this rather than simple inspection? How many positive divisors of 192 are also multiples of 6?

I think as big as in D is being misued. as big as indicates a comparison, but here it is comparing 30 feet long to whale, sort of a slang usage.

For anyone who has taken the practice kaplan tests on the cd that comes with the book, what's a good score? do you think they are indicative of the real test? I've been getting 50s on them and feel like they might be too easy. (I took the real test once and the math was MUCH harder than the og powerprep) the verbal portion of the kaplan seems like garbage to me, overly vague questions that are too difficult.

I believe that the rule is that 'the number' is always singular and 'a number' is plural. from the kaplan verbal workbook

you might have seen this , from kaplan : However much parents in Johannson's district may agree that the instruction of moral values should take place in the elementary school classroom, it is difficult...... A B. Despite the fact that parents in Joh. district may agree that C. There is general agreement among the parents in Joh's district that D. Although the parents in Joh's district agree for E. Even though the parents in Joh's district agree I eliminated B because despite the fact cant go with may agree, C seems wordy, and in D agree for is incorrect. So between A and E, why does A win, that is why do I need a THAT after agree??

just as means the same thing as 'in the same way that' from the sentence correction notes. i guess this makes sense in the sentence, and the idiom is just as, so.... so i think B

an = 2an – x what does this mean? not clear at all

It lists the correct answer as E. i got this wrong. i think the noun manifestations and the verb manifested mean different things. here we need manifested, meaning something like demonstrated

This is taken from a paper GMAT, the correct answer is C. we need a like here b/c no clause in the comparison. in D i think 'the use of which' is probably too wordy for the gmat and it's not very clear what it's referring to. the dash indicates change of thought

Manifestations of Islamic political militancy in the first period of religious reformism were the rise of the Wahhabis in Arabia, the Sanusi in Cyrenaica, the Fulani in Nigeria, the Mahdi in the Sudan, and the victory of the Usuli "mujtahids" in Shiite Iran and Iraq.

thank you, in my haste i said 10/48 = 5/19 not 5/24 which would be 5 to 19. duh. i like how this question makes you distinguish between ratios and fractions

:mad: Hear me through here for a second - In A we have a ratio of 1 to 3 or 25% alchohol. We take 8 ounces of it, meaning 2 ounces of alcohol and put it in B. B was 1 to 9 or 10% alcohol so it's original 40 contained 4 ounces of alcohol. after the addition of A we have 48 total ounces with 4+2 = 6 ounces of alcohol. Take 16 ounces of this , which will contain 2 ounces of alchol and add it back to A, which was 32 with 8 and now will be 10 ounes of alcohol out of 48 total ounces. So in fractional terms we're at 5/19. Is this the same as the ratio though? it seems like it would be 5 parts alcohol to 14 parts water???? Where am i screwing this up?

of course, 2 equations with 2 unknowns. However, the answer is A..... find numbers that fit A and then see that they fit the original. How do you turn 1) into the stem though?

taken from princeton review, they say to figure this out by subsitution but i would like to know how to do it algebraically: what is the value of (2a+b)/(a+b) 1) 3a/(a+b)=7 2) a+b =3

In terms of formal logic, A and B are equivalent. doubtful gmat will check whether you can differentiate b/w if a then b and b only if a

yeah, i screwed that up, i meant 50. the -20 should not be there

I think : we can go odd odd odd or even even odd, so the first ball can be either or and then you need the other two. (1*.5*.5)+(1*.5*.5) = 1/2

100% = 75 + 55 - both + neither = 130 - 20 - both + 20 = 30

/x-2/ the way i understand you find the roots is first just drop the abs values x-2 the x cancels out so this is always true (please correct me if that's incorrect) to get other root put -(x-2) -x+2 -2x x I go back and inspect to see that while -1/2 is the cutoff point, my sign is reversed (perhaps you have to reverse it when you put the neg in front of the one side?) anyway, the ans is x>-1/2

I think it's E, the stem should say something about x or y, you can't relate them

I figured out how many multiples of 5 are there b/w 5 to 1000. (995/5)+1 = 200. get rid of half of these so 100. 100 numbers with the average number being 500 = 50000.

we need our # to include the prime factors 5 5 and 3 3 3. the 6^2 covers 3 3 so we still need a 3 * 5 * 5 = 75

From princeton review, it's C
