Forget it. I got it.. Took me a minute. Had to write it down. Thanks.

You are right, I wrote it wrong. Thanks for the reply. Can you elaborate a little further on what the equation is actually saying. Thanks.

When a certain tree was first planted, it was 4 feet tall, and the height of the tree increased by a constant amount each year for the next 6 years. At the end of the 6th year, the tree was 1/5 taller than it was at the end of the 6th year. By how many feet did the height of the tree increase each year? a)3/10 b)2/5 c)1/2 d)2/3 e)6/5 OA: Trying to review all of my incorrect answers from my GPREP test, so sorry for all the requests. Thanks for all of your help:

Thanks for the answer, and the formula.

Thanks so much for the reponses.

The value of 10^8 - 10^2/10^7-10^3 is closest to which of the following? a)1 b)10 c)10^2 d)10^3 e)10^4 OA I can get the answer to this problem basically by factoring out 10^2 from the top and bottom, and then using basically brute force and just creating a fraction with the results on the top and bottom and dividing. It is not exact, but it does give me a number close to the correct answer, and the question asks for the closest. I was wondering if maybe there is a better way to do this problem.

I would think this would be an easy problem, but I am having a bit of trouble with it: If the speed of x meters per second is equivalent to the speed of y kilometers per hour, what is y in terms of x? (1 kilometer = 1000 meters) a) 5x/18 b)6x/5 c)18x/5 d)60x e)3,600,000x OA: I was assuming I would be multiplying by 60 and then 60 again. I tried plugging in numbers. Any help would be appreciated. Thanks guys.

I was hoping some of you guys (gals) could explain how to get this answer: If the chance of pulling two cards from a stack of uniquely numbered cards (without replacement) and getting the five and six is 0.10, then how many cards are in the stack? (A) 2 (B) 4 © 5 (D) 11 (E) 12

Thank you so much (all of you) for your help with this. I understand it completely now. It was actually much simpler than I thought it was. Also, DWarrior, thanks for the link. I went over the document and it was really good, and helped me understand combinations and permutations much better. I think the hardest part is just knowing when to use or the other, and also knowing when you have to use both.

I get what you are saying. But, I am a little confused the notation "c", when you say 3C1.

I was wondering if someone can explain to me how to the following problem. I have read an explanation for it, but i am still a little lost: How many different arrangements of letters are possible if three letters are chosen from the letters A through E and the letters E and A must be among the letters selected? (A) 72 (B) 64 © 36 (D) 18 (E) 6 OA:

Velman, I guess you decided to sign up for BellCurves. I actually signed on here just to post this question, and saw that you had posted it. What do you think of it so far.

I use Bellcurves. It was recommended to me by one the posters who scored a 720 on the GMAT. I can only comment on the quant since I do not really use it for verbal. The quant questions are really good, and they seem similar to stuff that I saw on the real GMAT. Well, let me qualify that statement a little. Some of the questions on the Bellcurves site were similiar in style to questions I saw on the real GMAT. No exact duplicates or anything like that. The material on there did not teach me much as far as content, so you need to know the basics. I did learn some good tricks and new ways to look at problems. I also think you are given a good amount of feedback from the drills and homeworks. I will post again in a few weeks after I take the test to let you know how well the results were for me.

I have been curious about something for a while, and it has been very hard to find the answer to this question online. Pretty much everyone you speak to about B school admissions will tell you that underepresented US minorites have an advantage in the admissions process, but no one really ever explains in what way. How does a school evaluate a minority candidate in comparison to non-minority candidates? Do they discount the GMAT score, or GPA? Do they assume that minority candidates will have a lower gmat score based on some national score distribution based on demographics? It seems like no school is really straightforward on this, and I can figure out why. I am just curious if anyone here has any realy insight into this. Thanks.

I kind of just went in and did not really give any thought to the AWA. I just looked it as something I needed to do before I got to the real test. I am a decent writer so I did not think it would be too hard for me. All I did was write an intro paragraph, discuss some ideas in about two to three paragraphs, and then write a conclusion. To be honest, the topics are rather generic since they can not expect you to know too much about certain subjects, so I do not think they are too concerened with content. I pretty much wrote junk, I just structured it well. I did look over some documents I found on the web the day of the test that go over a template approach to writing the essays. It is pretty much just standard essay writing stuff.

I definetely think running out of time was an issue for me with my quant score. I did have to guess on some questions towards the end. The problem is, I am not really comfortable in many of the topics in quant. I mean, I get all the easy questions right, I just get tripped up on medium to hard questions. In other words, if I do the questions in the OG 11 book, I am perfect up until the last 3rd of the book. Then, I hit a wall. I have been spending time reviewing all the quant material from the beginning. I basically am putting myself through school for a few weeks. I signed up at a site called bellcurves.com that another poster (TBAY) suggested in one of his posts. I felt I needed to do this since I had exausted all the OG 10 and OG 11 questions, and it is difficult to really get good explanations on the questions from the SETS. So far so good with the site. I feel like I am building up my quant skills, and they have homeworks and drills to test you to see how you are progressing. I do not think the site is for everyone. I just think it is good for me since quant is my real weakness. They also have verbal stuff, but I do not think its that great, plus, I need to spend a lot more time on my quant right now. One thing I noticed is that I that taking the test for the first time was good for me. I do not think the practice tests can really simulate the whole expierience of taking the test for real. I feel I know what the test is going to throw at me now, and I am not as afraid of it. I think I am going to do much better next time.

Not that its any consolation whatsoever, but I got a 6 on my AWA.

Does anyone know?

It is strange. Everyone keeps saying how it is so much easier to improve your quant skills quickly, but I am not sure exactly how to go about doing that. Nothing has worked for me so far. Any ideas?

Well, after studying for about 4 months, I can not put into words how dissapointed I am. Not sure how it will help you guys, but here is my debrief: Started studying in May. Took a Manhattan GMAT in-person course, which I thought was pretty good. Obviously, quant is my weak subject, so I went through all the MGMAT books, and they definetly helped with the basic concepts. I then spent another month going over the 10th and 11th edition and some of the stuff I found on this site. Here are my practice scores: MGMAT 1: 510 MGMAT 2: 540 MGMAT 3: 650 (40Q 39V) GMATPrep 1: 640 (38Q 39V) GMATPrep 2: 610 (34Q 41V) (Two days before the exam) I also took some paper tests and did some of the sets. I knew that 700 was going to be a long shot based on my practice scores, but I had already scheduled the test, and I wanted to experience the real thing. I am not sure what went wrong in my last week of studying. My quant scores started to go downhill, and I could not fix it. I think I might have burnt myself out a little bit since I seemed to have peaked at around 640 - 650 and then started dropping. So, the test experience: Got there an hour early. I was fingerprinted, and had my picture taken. I was not really that nervous. The AWA went OK. Nothing too out of the ordinary. Not sure what my score was, but I assume I did fine. Took my 10 minute break and then started the quant. One note, be carefull with your usage of the dry erase board they give you. They give you one at a time, and if you run out of space, you need to get the attention of the administrator to get a new one. This cost me at least a minute on the quant section. Quant: After the first question in the quant section, I was uncomfortable. Lots of number property questions. Nothing too crazy, but I would say the quant section is representitive of only the last 50 questions in the OG 11. Anything before that is way easier than the actual exam. I am obviously not good enough at quant to give a good analysis of the entire section, but it was hard for me. I also was running out of time towards the end of the section., and this caused me to guess on a bunch of questions. Verbal: WAY harder than I thought it would be. I felt great for the 1st 10 questions, after that the questions got crazy. Almost all of my CR questions were in different formats than what you normally see in the OG or the GMATPrep tests. I kept getting weird formats. For example, I got several questions where I was asked to finish a paragraph, and I got a few with two people having a debate, and I was asked to analyze that debate. They were very tricky. Then I got the RC passage from hell. It was a 5 (long) paragraph passage about insect evolution through different time periods of the Earth. I am a great reader, and I would have needed 20 minutes to really understand what the passage was talking about. I think I got all four of the questions wrong, and that is probably what brought my verbal score down a bit. The SC questions were nothing out of the ordinary, but I did get some really difficult questions. I even got one where all of the anwer choices had the word "being" in it, except one that was obviously wrong. Anyone who studies SC usually finds out that being is almost always wrong. I guess GMAC figured this out and decided to throw a curve ball at me. I knew I had done bad in the math, but I guess I was just hoping for the best. When I saw my score, my jaw dropped. I have not gotten a score this low since my 3rd week of studying. I honestly think I did not simulate the test experience enough in my studying. I took practice exams, but not as often as I should have. I spent a lot of time going through the 11th and 10th OG, but not always under times conditions. My math background is horrible so I needed to learn the basics, and this took a while. I originally scored a 24 on the Quant in my first practice exam. I also think I studied a little too much in the last week, and I burnt out. There also is no feeling like when you actually sit down in that room and know it is for real. I guess I hit rock bottom. I am going to take the weekend off, and then go back at it. I will come up with a better strategy this time around. I will also go back and analyze every question I get wrong on the practice exams so I know how to solve every type of problem. It is hard to be perfect number properties because there are so many types of problems. I guess I will take the test again one month from today and that should give me enough time to make round two. If anyone has any good suggestions for improving quant, let me know. I will say that this forum was very helpful for me, and it is the reason that I am able to shake this bad performance off and get right back on the horse. Hope to be reporting back with a better score in a month.

Does a 41 Verbal and a 40 Quant really add up to 690? I would have thought the over all score would be a little lower.

I am not sure about the Kaplan software, but I was told by an instructor that the two statements in DS will never contradict each other. So, if the answer is D, than both answers you get should be the same if you decide to work the both out.

Will do. Thanks. Trying to get as much in before the test. Question: Do you guys think doing the 150 GMATPrep questions is better practicethan the sets?

Q35: If n is a positive integer, which of the following is a possible value of |56 - 5n|? A. 7 B. 9 C. 12 D. 15 E. 20 OA For some reason, I could not work this one out. I figured the answer would be negative, and then the absolute value of that number would be here. I tried to solve by just plugging in different numbers for N, and could not get any that worked. Is there a better way to solve?

Also from SET 22: Q16: In the sequence of nonzero numbers t1, t2, t3, …, tn, …, tn+1 = tn / 2 for all positive integers n. What is the value of t5? (1) t3 = 1/4 (2) t1 - t5 = 15/16 OA Can someone help me work this one out?
