I would look at each number. A for example, by simple mental math, you can tell that 420 divides into 7 60 times, and obviously 6 does too then. Five will divide into 420, as well as 4 and 3, and its a given that 2 will as well. A.

Congrats, I hope that your apps go well. Nice work on the quat end... I'm looking into Kellogg and U of Chicago GSB as well...

Great job, thank you for the debrief. Where did you obtain all of the paper GMAC tests? That's a lot of them!

Sounds like a good plan. I myself am working through the MGMAT SC guide right now, which is very well written. I did not sign up at Manhattan GMAT's website yet though, as every time I look in my SC book, I forget to take it to the computer to copy over the website to sign up and view/take their CATs.... I love math, and am pretty good at it, and because of this, it is my greatest fear on the GMAT. I do not want to rush through any of the problems...

I am taking mine on or around April 1st, who else has their exam scheduled for the month of April? What sections are you on and how have you been scoring? April GMATers unite! :tup:

I think since you know the square root of 4 is 2, and the square root of 9 is 3, there are 5 numbers between 4 and 9 (9 - 4 = 5) and 5 is 1/5 of the way to 9, so figure approximately 2.2 is the square root of 5. Given that, 1+2.2 = 3.2 to 2. So now that you have that, find out which answer this is a factor of. If you take A, multiply it by 2.5, the result is 8 to 5. A works.

That is correct. I think that the question is referring to the sample of numbers pulled from the 1,000. If the mean of the total population is 8.1, this does not necessarily represent the mean of the sample. My whole difficulty in believing this answer is that it's next to impossible to come up with the standard deviation from the mean using the sample and then comparing it to the results, all in under 90 seconds? It seems too complex of a question.

How do you know that the sequence repeats itself every 4 terms, given an = an-4 for n>4? I guess I am confused by the an = an-4 part. This is NOT an(-4) correct?

I'm not 100% certain on this answer... If it takes this car 62 seconds to travel 1km as the other car who travels the distance in 60 seconds.... At 75km per hour, it takes 62 seconds to travel the same distance. 75/62 = 1.2099 1.2099 * 60 = 72.040 or approximately 72km/h I would choose B.

Don't forget the Manhattan GMAT SC guide!

I've purchased OG11 recently as well as Kaplan 800. I have just received these texts. I plan on investigating the Manhattan material further shortly. I would like to take the GMAT in the beginning of 2008. I am getting married in fall and then honeymooning for 15 days, so studying intensly in the next few months is not going to happen. I would like to casually browse through the texts though until I have the proper amount of time to devote weekly in the winter and early next year. Do you recommend that I take an exam prior to doing any reviewing? I am curious as to what progression I should take, give that I am unsure where I will need more review. I have a finance degree that I obtained in 2002 and I work at a financial firm right now. I was born and grew up in Chicago, IL. By the way, the debriefs on here are great, I do learn a lot from them, especially which texts will help me to focus on what areas.

Great job on the exam and excellent debrief. Thank you for providing your process in great detail!
