What is the OA? I pick D

Hi Everyone, I have a discrepancy with MGMAT materials: the sentence correction idiom chapters says IN COMPARISON WITH is used for UNLIKE things while IN COMPARISON TO is used with LIKE things. However, a practice question on MGMAT's cat exam reverses the relationships. What is correct? ~*~*~*~*~*~*~*~* Example: In comparison with tropical cyclone systems, subtropical cyclone systems have a relatively broad zone of maximum winds located farther from the center, and typically have a less symmetric wind field. When describing the similarities between unlike things, the idiom “compare to” is used. When describing the differences between like things, the idiom “compare with” is used. In this sentence, differences between two like things, a tropical cyclone systems and subtropical cyclone systems, are discussed. Therefore, the idiom “in comparison with” is the correct choice.

I want to echo the strange scoring on Princeton exams. I bought the "cracking the GMAT book" and received 4 online CAT exams. I am scoring 700 to 720 on MGMAT and GMAT TestPrep software, however, only mid to high 600s on the Princeton. The most recent one was a 650, however, I hardly missed any questions! Just curious is anyone has had a similar experience

Minuddin and everyone else, Thanks for the responses. I understand 2 and 3, but question 1 is a mystery. The answer is E. The question is from the GMATPrep software. Is there a way to view an explanation to the solution? The software tells you the answer, but does not explain the answer. Hopefully someone can figure out why it is E

i can't get this link to work. is it possible for someone to please post?

Hello, I recently did a CAT exam. I missed a few questions on Math and, unfortunately, there is no explanation for the solution. I hoped the wizards here could please help. I would love to hear how you would solve any of these problems 1. For every positive even integer n, the function h(n) is defined to be the product of all even integers from 2 to n, inclusive. If p is the smallest prime factor of h(100) +1, then p is A. b/n 2 and 10 B. b/n 10 and 20 C. b/n 20 and 30 D. b/n 30 and 40 E. Greater than 40 2. If x 0, then square root (x^2) / x = A. -1 B. 0 C. 1 D. x E. abs(x)/x I thought it was c, but no dice 3. For which of the following functions is f(a+b) = f(a) + f(b) for all positive numbers a and b A. f(x) = x^2 B. f(x) = x +1 C. f(x) = sqr (x) D. f(x) = 2/x E. f(x) = -3x Thank you kindly

Check out the math books from EZ Solutions. Very detailed and excellent if you can get past a few printing mistakes. Also, I like ManhattanGMAT's books. They do a nice job with laying out productive approaches to all types of problems.

Awesome reply. Thank you! :)

you have to let them know a week in advance, so call them asap! if not, say bye bye bye to your $250

i am taking the gmat next week...i've done all 6 mgmat's cat exams and am now trying princeton's tests...princeton questions are FAR easier than mgmat...however, the scoring on princeton seems strange princeton is a nice extra tool, but i am glad i didn't use for the core of my studying

i noticed the same thing...however, i don't believe there are additional free exams outside of the prep software...

I need some help with digesting the answer to this question: Six mobsters have arrived at the theater for the premiere of the film “Goodbuddies.” One of the mobsters, Frankie, is an informer, and he's afraid that another member of his crew, Joey, is on to him. Frankie, wanting to keep Joey in his sights, insists upon standing behind Joey in line at the concession stand, though not necessarily right behind him. How many ways can the six arrange themselves in line such that Frankie’s requirement is satisfied? The answer: Ignoring Frankie's requirement for a moment, observe that the six mobsters can be arranged 6! or 6 x 5 x 4 x 3 x 2 x 1 = 720 different ways in the concession stand line. In each of those 720 arrangements, Frankie must be either ahead of or behind Joey. Logically, since the combinations favor neither Frankie nor Joey, each would be behind the other in precisely half of the arrangements. Therefore, in order to satisfy Frankie's requirement, the six mobsters could be arranged in 720/2 = 360 different ways. My thoughts: I understand the 6! There are 720 arrangements without the constraint. However, I don't understand why we divide by 2. I would think that since Frankie wants to stand behind Joey, the limitations would be: Slot 1: Joey, Frankie has 5 choices Slot 2: Joey, Frankie has 4 choices Slot 3: Joey, Frankie has 3 choices and so on. Thanks in advance

thanks for the responses...my timing has improved...i certainly need the full 75 minutes for math kaplan's math books had some helpful timing sets, fyi

yes, i believe they are the same

I have trouble reducing my timing for this section. I am practicing a lot, but have a tough time finishing 37 questions in the 75 minute time slot. Any recommendations? Does it make sense to take a "slow and steady" approach to the exam or is it best to work under the "2 minutes per problem" rule. I'd greatly appreciate any help. Thank you!
