In the Quant section of the GmatPrep test, I am consistently getting 10-13 questions wrong. My current score is Q49 but I need to stretch it to Q50.

I have given 2 GmatPrep tests and in each test, I got around 6-8 DS questions wrong.

Math experts: Any suggestions/strategies to go from Q49 to Q50 in 15 days. I have my exam coming up In addition, any specific DS material (theory/practice) that can help me here??

Hi Fluke,

Thats right. I have got Q49 in 2 consecutive GmatPrep v2006 tests. In the first test, I got 13 incorrect, and in the second test I got 10 incorrect.

If you feel that my Quant score is not as per GMAT standard and you feel that i should have got less than Q49, then kindly tell me how many questions does anyone generally get wrong with a Q49 score.

I did the analysis of DS questions and found that my incorrect DS questions were mainly from ratio, percentage, numbers, inequalities, algebra, stats, modulus.

Please guide me in how to get to Q50. Any recommended theory material or practice questions?

In addition, how many questions should I ideally get wrong to get to Q50?

Sorry, no idea!!! I have little to no experience with GMATPrep and my doubt was genuine. I just don't understand how these numbers are calculated. I always go by the number of questions I solve correctly and my threshold is at most 5 questions wrong. Any figure worse than that doesn't appease me. There was another reason for me to wonder: we solve 37 questions and get a score between 0 and 60. Thus, every question should carry a weightage of presumably more than 1 mark, if you answered 10 wrong; 60-10=50. Now, your score will be below 50. There is also some rule regarding answering a lower level question over a higher level question. Arrrghhh!!! It gets so confusing that unlike many students, I just overlook all that grading and just focus on the numbers of questions.

Guess someone like IanStewart or Karishma can answer this question to your satisfaction.

Regarding boosting your marks in the DS section, practice is virtue.

2. Solve 1000DS, because: a. It contains real GMAT questions from the past. b. The questions are not unrealistically difficult. c. The questions are spread across all topics.

The questions do not have detailed solutions. You will have to search through GMATClub or google to get solutions, which may be time consuming but you will surely get an excellent practice out of these.

Don't doubt your GMAT Prep score. Check out this article to learn more about the GMAT algorithm. http://www.veritasprep.com/blog/2010/08 ... algorithm/ If you would rather not spend the time, know this: those scoring in the 46-50 scaled score range on the quant section (the upper limit of high scores) answer between 21 and 26 of the 37 math questions correctly. You can score well above the 90th percentile on math and miss more than a dozen questions! (And if you’re good enough at math to do that, you’ll note that it equates to your missing roughly a third of the questions)

I like to discuss holistic approaches rather than following-a-process approach. If you view the big picture, you can get through your questions much faster. DS questions use the same concepts as PS. The only difference is that they are trickier and take a little longer since, on an average, you solve two questions (one for each statement) for each DS question. Veritas has a separate DS book available on Amazon if you would like to take a look at it for strategies and pitfalls.

Very importantly, don't freak yourself out. Q49 and Q50 are not that far apart. If you keep your cool, take good rest and relax, you might anyway make it without extra effort (but if I were you, I would put in some effort and keep my cool too to double my chances!!!)
