The Application Process :: Optional Essay to Explain Low Quant Score?

Subject: Optional Essay to Explain Low Quant Score?
Posted: Fri Mar 13, 2015 10:44 pm (GMT -8)

I'm applying to various Master of Science in Finance programs. My GMAT score is acceptable (710). However, my quant score is relatively low (45 or 63%). Most of the programs I'm looking at have an average score of around 680-730, so my 710 is within range for most schools. However, my quant score is on the lower side.

If it makes a difference, I don't have much of a quantitative background (single variable calc, intro stats, intro probability) and a bunch of accounting courses. I've gotten A grades in all my math courses and mostly A/A- grades in my accounting courses.

I'm hesitant to use the optional essay as I don't want to sound whiny. However, I also know my quant score could be higher for the schools I'm looking at.

appreciate any opinions!

You pose an interesting question, "how to solve?" but remember this is a DS question, so our job is not to solve, simply to determine whether a statement is sufficient TO solve. Smile It's some comfort that we don't actually have to DO the hard work on DS.

That said, here's how I'd break it down:

This is a VALUE question. We want to know # of residents who DO NOT own a VCR or DVD. The givens:

-4,500 residents = VCR, DVD, or both

A matrix is best used when we have multiple categories with choices WITHIN each category. For example, if this question was Residents/Non-Residents in addition to VCR/DVD, then a double-set matrix would be a smart choice. But because we're only looking at VCR/DVD + an overlap, so a Venn Diagram is a better option if you're looking to express the givens in a visual format.



This VALUE question is asking us the value of the question-mark. We need to know the TOTAL residents so we could subtract the 4,200 to identify the number of residents who are OUTSIDE the Venn.

Now we can analyze the statements:

1) This says that X + Y = 4,200, but without knowing the total residents in Reytown and the value of Z ("both"), we cannot find the value of "Neither." Insufficient.

2) This tells us 10% own neither, and we know that 4,500 = X + Y + Z. So that 4,500 must equal 90% of the total.

4,500 = .9(T)

Sufficient.

Here's a problem in which a matrix would be useful:

33 out of the 47 students in an advanced degree program have a higher than average GPA. How many students in the program are receiving some form of academic scholarship?

(1) More students do not have a scholarship than have a scholarship.

(2) The same number of students have a higher than average GPA and are receiving some form of academic scholarship as have neither a higher than average GPA nor an academic scholarship.

Solution:

From the question-stem, we know 33 students have a high GPA, while 14 do not. We need more information about which of these students have scholarships to be able to answer this value question. Notice how the categories are more complicated in this question than in the previous question, since we've got higher than average/lower than average and earning a scholarship/not earning a scholarship.

Statement (1) is insufficient because it does not give us information to find the exact numerical value of the students receiving some form of scholarship.

Statement (2) tells us that the number of students who fit “both” is equal to the number of students who fit “neither.” Let’s set up a chart to visualize the four possible categories for the students. Since “both” = “neither,” let’s fill in “x” for those boxes.

The key to the double-set matrix is to make sure you have a vertical and a horizontal "TOTAL" column:



Since each column and row must total, if there are “x” students receiving no scholarship and not a higher GPA, and the total students who don’t have a higher GPA is 14, then 14-x students must not have a higher GPA and have a scholarship. The total we are looking for is represented by the red “?,” and we can set up an equation to solve: x + (14 – x) = 14. Sufficient. The answer is (B).

Hope this helps!

Best,
Vivian

Notice that on the number line, the overall average of 11.625 is closer to A (10.2) than it is to B (14)

10.2----11.625----------14

Therefore, we must have more A than B. If A > B, only option that works is B

Quote:
On a scale that measures the intensity of a certain phenomenon, a reading of n+1 corresponds to an intensity that is 10 times the intensity corresponding to a reading of n. On that scale, the intensity corresponding to a reading of 8 is how many times as great as the intensity corresponding to a reading of 3?

a)5 b)50 c)10^5 d)5^10 e)8^10 - 3^10
A reading of n+1 corresponds to an intensity that is 10 times the intensity corresponding to a reading of n.
Put another way:
Every time we move up one position in the scale, the intensity is multiplied by a FACTOR OF 10.
Thus:
A reading of 2 is 10 times a reading of 1.
A reading of 3 is 10 times a reading of 2.
A reading of 4 is 10 times a reading of 3.

A reading of 8 is how many times...a reading of 3?
Let a reading of 3 = 1.
Since every subsequent reading increases by a factor of 10, we get:
Reading of 4 = 10*1 = 10.
Reading of 5 = 10*10 = 100.
Reading of 6 = 10*100 = 1000.
Reading of 7 = 10*1000 = 10,000.
Reading of 8 = 10*10,000 = 100,000.

Since a reading of 8 = 100,000 and a reading of 3 = 1, a reading of 8 is 100,000 times a reading of 3.

The correct answer is C.

Hello could someone help me to solve this problem?

A mixture of two candies, A and B, costs
$11.625 per kilogram. Candy A costs $10.2
per kilogram while candy B costs $14 per
kilogram. What is the ratio A:B in which the
two candies are mixed?
A) 3:5
B) 5:3
C) 3:8
D) 5:8
E) 3:4
Cost of A = 10.2.
Cost of B = 14.
Cost of the MIXTURE of A and B = 11.625.

The following approach is called ALLIGATION -- a very efficient way to handle MIXTURE PROBLEMS.

Step 1: Plot the 3 prices on a number line, with the prices for A and B on the ends and the price for the mixture in the middle.
A 10.2--------------11.625--------------14 B

Step 2: Calculate the distances between the prices.
A 10.2----1.425-----11.625----2.375-----14 B

Step 3: Determine the ratio in the mixture.
The required rate of A to B is equal to the RECIPROCAL of the distances in red.
A:B = 2.375/1.425 = 5/3.

The correct answer is B.

As David notes above, since the cost of the mixture (11.625) is closer to A's cost (10.2) than to B's cost (14), the mixture must contain more A than B.
Only B offers a ratio with more A than B.

I am looking for assistance and some serious help. I think there is a fundamental flaw in the way I approach verbal section. Coming from a technological back-ground I have no issue at all with the Quantitative section, even with some goofs up and some silly experiments (To test the scoring algorithm in two CATs and actual Exam) I have always managed score above 40. My verbal part is really poor; I never have crossed 30 even in any of the two Manhattan CATs that I have finished so far. I am consistently scoring between 22 to 25 mark.

It should read as follows:

planet is approximately 2.3 X 10^14 inches. Which of the
following is closest to the average distance between
the Sun and the planet, in kilometers? (1 kilometer is

(D) 1.6 X 10^11
(E) 5.9 X 10^11
As for your question:

Priyaranjan wrote:

(2.3 * 10¹⁴)/(3.9 * 10⁴) ≈ 2/3 * 10¹⁰ ≈ 0.66 * 10¹⁰ = 6.6 * 10⁹.

The closest answer choice is B.

DS is funny and takes specific skills and knowing about tricks they use, such as C traps. So it figures that most of the ones you didn't get right were DS questions.

By the time you go through all the DS questions in the Official Guide you will be much better at DS. Then you could do more DS questions as necessary. From the sound of it, you are not to far from Q51, and maybe once you have gone through the Official Guide math section you will be almost, or completely, there.

As Vivian says, make sure to track what you don't get right so that you can focus on learning about what it takes to get those questions right too. Also, myself, I tend to realize that I am not comfortable when questions of certain types show up. When you know what your are more challenged by, learn all the angles related to each type and do questions until you are comfortable with each type.

Approximately one in thirty-three people scores Q51, by the way. So doing that is not even close to being unachievable.

As far as verbal goes, it's not that difficult. Most of what it takes to get verbal questions right is clear thinking and attention to detail, and without those things you won't get verbal questions right no matter what strategies you use. In other words, don't get so caught up in verbal strategies that you don't see the forest for the trees.

The CR Bible Chapter 2 has in it some key concepts you need for getting CR right. That can be your foundation. Then you could learn some more, but getting CR right is in a way mostly about seeing logic clearly and not getting smoked by trick answers.

RC also takes not getting smoked by trick answers that seem right. The details will get you.

SC might take some learning rules and stuff. At the same time, much of getting SC right is about hacking your way to right answers. I recently took the GMAT again and found the SC questions to be rather hackable, and I think that's how they, GMAC people, like it. That's the point right? Though SC could be tough if you were clueless about grammar and idioms, it's not really about knowing every little rule. SC and communicating effectively are mostly about knowing how to structure language in ways that make sense. So, sure, learn rules and idioms, but also get good at hacking the questions.

So there are some things to consider as you prepare.
