Hi Amit,

Which test do u plan to take today ? and otherwise also..which tests do u suggest we should take that would give us an accurate idea as to where we actually stand ? i have heard that Powerprep software on mba.com gives us a fair idea.i have been trying to download it for weeks now.but i m unable to do so. :(

Guptaaastha,

Try the crack-gmat.com free full length diagnostic test. I thought it was close to the real GMAT CAT.

If you buy the Princeton review material, it comes with 4 full length tests, which are of decent quality too.

GMATPrep has two full length CATs, you can take one of those two ( only if you want to

gange your skills for sure, otherwise I suggest you to keep both these), and reserve the second for taking it just before the real GMAT CAT.

Also there are quite a few paper based tests ( example, retired ETS ) which have a mix of easy and hard questions that you can use for practice ( esnips download contains many of these paper based stuff )..

Hopefully you find this useful and get going with your preparation.

Cheers,

and regarding the materials.... i just have the OG11 hard copy with me which i got it from a friend. and a lot of online material as softcopies which i collected while doing lot of research on gmat a couple of months back....

so if anybody wants any material you can let me know and i can check if i have it....its nothing new...collected from the same sources mentioned all over pagalguy.....

and can anybody suggest me which books hardcopies are needed in any situation and where i can get them in bangalore.. . i just know the regular places like sapna book stores,gangarams,book paradise, so suggestions of any cheap places are most welcome ....and is it advisable to spend on new copies or if we get hold of some second hand copies,its good enough???

ok hoping for a quick reply......

c ya.......enjoy!!!!

Avinash,

Good to know about your interest. And I welcome you aboard.

For the question related to which material you should buy ( physical form ),

Kaplan 800

OG-11 ( which you already have )

should suffice the need considering that you have the other xsniped stuff like OG-10, 1000 SC/CR, manhattan, Nova etc....

Start with Kaplan 800 , becoz , it nicely explains each of the answer choices, why

correct/incorrect. Once you are done, you would have already swallowed a medicine

of high performance, which will give you enough strength to attack the OG-11 and

eventually the official GMAT exam

Good luck in your pprn !

Cheers,

ChivaS.

Hi Amit,

I have not given a lot of tests. I am working as well so its kinda tough to give a lot of time to studies..I gave like 2-3 tests and was not able to cross 600 in any of them. I m very comfortable with the Maths sections and manage to get around 34-35 correct but Verbal is a problem for me. I just cant get the Reading Comprehension and Sentence correction right. Hope to improve my score in the near future.

Does anyone have any suggestions ?

Aastha! :)

Aastha,

Practice, Practice and Practice .

Thats it ! there is no easy way to success in GMAT for those who are not as good in Verbal

sections ( types ME )

My scores started improving ( though my starting score was 660, and aiming to add a hundred) , once I completed Manhattan SC, and then did some practice in OG-10 ( especially SC part ). CR is ever OK for me ( not the best though). For reading comprehension, there are some tips'n'tricks by Funnan sometime ago " which are basically extracts from GIN's posts" please look around for possts by Funnan in GMAT Prep materials, if you can't locate, I will give a try and send it across.

Cheers,

Hi,

Answer to first one is "B" and 2nd one is -"D".....

I didn't get the 2nd one...It says with the help of chemicals they are able to emerge from the cyst but nothing explains why they will starve to death.It might be possible that they emerge from the cyst and are still active when potato crops are laid.Please explain....

Cheers

Naive

I think answer choice D explains it :)

Because the option says, spreading of chemical in potato fields

makes the nemetodes come out of the cyst.

And then, look back to the manifacturer's suggestion to spread the

chemical while the potatos are not planned.

So, option D quantitatively explains that 90% of nematodes indeed emerge from their cysts and if the chemical is used while potatoes are not planned "starvation" logic is explained.

Puys ! one more DS qn!x > y > 0. If x and y are integers, is y even?(1) x - y = 1(2) 2x + y = 32

A,B,C,D,E , just the usual DS answer choices ( 1 alone, 2 alone etc ... )

Hey Puys, one small DS question,

Give it a try , I will post the answer with explaination by evening today!

If the square root of the product of three distinct positive integers is equal to the largest of the three numbers, what is the product of the two smaller numbers?

(1) The largest number of the three distinct numbers is 12.

(2) The average (arithmetic mean) of the three numbers is 20/3A, B , C , D , E are,as per DS standard answer choices. (1 alone, 2 along etc....)

If you call the three numbers x, y and z, and let x be the biggest, then the question tells you that x = square root of the product of x, y and z. If you square both sides of this equation you get:

x = xyz (which gets rid of the square root). Dividing both sides by x gives you:

x = yz.

So, if you can find a value for x, you can answer the question, which ONLY asks for 'the product of the smaller numbers'.

Statement (1) tells you that x is 12, plug that into x = yz and you get: yz = 12 (because the question asks "what is the product of the two smaller numbers?", this is what you are looking for and it is sufficient.)

Statement (2) tells you that (x + y + z)/3 = 20/3. Now, if x = yz and x + y + z = 20, then the only possibility is (2,6) and (12) as the (y, z) and (x). Every other combination of three integers summing up to 20 fails. 1,2,17; 1,3,16; 1,4,15; 1,5,14; 1,6,13; 1,7,12; 1,8,11; 1,9,10; 2,3,15; 2,4,14; 2,5,13; 2,6,12; 2,7,11; 2,8,10; 3,4,13; 3,5,12; 3,6,11; 3,7,10; 3,8,9; 4,5,11; 4,6,10; 4,7,9; 5,6,9; 5,7,8; and that's the end of the possible combinations of three integers whose sum equals 20. The only combination that works is 2,6,12. If it were 1,9,10, then yz would not equal x. If it were any other combination, such as 5,7,8, then yz would not equal x. The only solution is 2,6,12. This means that yes, Statement 2 is sufficient because the product of yz is 12. Note: this is an extremely hard question that few students get right.

Since both statements are sufficient, the answer is D.

Anyother time saving tips/tricks are welcome.

1. In the traditional Japanese household, most clothing could be packed flatly, and so it was not necessary to have elaborate closet facilities.

(A) flatly, and so it was not necessary to have elaborate closet facilities

(B) flat, and so elaborate closet facilities were unnecessary

(D) flat, there being no necessity for elaborate closet facilities

(E) flatly, as no elaborate closet facilities were necessary

Choice : A.

2. In the minds of many people living in England, before Australia was Australia, it was the antipodes, the opposite pole to civilization, an obscure and unimaginable place that was considered the end of the world.

(D) that investigated changes in working conditions effects on workers performance

(E) to investigate what the effects changes in working conditions would have on workers performance

Choice : B : experiements investigating the effects that

chages in 'X' would have on 'Y'.

D: alterred the meaning :

investigated changes in working conditions' effects

rather than

investigated effets of "changes in wonrking conditions"

See the above file once X=7

sides are 7+6=13

7+8=15

Sharad, good explaination that the lengths of tangents from external point will be same.

So, the sides have to be x+6, x+8 ;

but then the later explaination in the solution diagram assumes that the extension of the

angular bisectors are going to become parpenticulars onto the apposite side, which may not hold good ( just think about it , perpenticulars are different from bisectors ).

This qn could be solved by Area= rs

Also from the answer choices we can eliminate the combinations that don't differ

by 2 , and the order given ( which one is shorter/longer ).

Cheers,

ChivaS
