The Quantitative section of the Graduate Management Admission Test measures the candidates’ ability to solve quantitative problems, interpret graphic data and of course the test taker’s ability to reason quantitatively.
There are two types of question in this section –
1. Problem Solving
2. Data Sufficiency
The two question types are intermingled throughout the section. Both types of questions require knowledge of basic high school standard arithmetic, elementary algebra and commonly known concepts of geometry. Advanced mathematics concepts are not tested in GMAT
The quantitative section comprises of 37 questions in all and the time limit is 75 minutes. Of the 31 questions, approximately 9 are experimental. These experimental questions do not contribute towards your score. However, the candidates cannot identify the experimental questions, which mean one has to treat all 37 questions with equal importance.
Your composite GMAT score is determined from a combination of your scores on the Math and Verbal section of the test. The composite GMAT score ranges from 200 to 800. However, the verbal and the quantitative section is graded separately and awarded raw score on a scale of 0 – 60. The awarding of the raw score takes into account the difficulty level of the question presented to you; how you answered and the number of question you have answered. Apart from the composite score (200-800), raw score (0-60) candidates are also awarded percentiles. A 95 percentile in Quantitative section means 95% of the candidates in the last four years have scored less than what you have scored. The average quantitative score in GMAT is 35.
Data-Sufficiency Questions Data
-Sufficiency questions measure a candidate’s ability to analyze a quantitative problem, identify the relevant information and determine at what point there is sufficient information to solve a problem. This type of question actually does not give solution to a problem but identify the necessary information required to solve it.
Data-Sufficiency questions are accompanied by some initial information and two statements, labeled (1) and (2). A candidate must decide whether the statements given offer enough data to enable him/her to answer the question. Five options are given and the test taker needs to choose one.
Sample – Data Sufficiency
1) Which of X, X^2, and 1/X has the least value?
2). X< 1
A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D. EACH statement ALONE is sufficient.
E. Statements (1) and (2) TOGETHER are NOT sufficient.
Problem-Solving questions test basic mathematical skills and a broad understanding of elementary and mathematical concepts. Advanced math is not tested here and a candidate is given a choice of five answers of which he/she has to pick one.
Sample: Problem solving
1) How many integers between 100 and 150, inclusive, can be evenly divided by neither 3 nor 5?
Answer: Number of all integers is 51.
Number of them divisible by 3 is (150-100)/3=17
Number of them divisible by 5 is (150-100)/5+1=11
Number of them divisible by 15 is (150-100)/15=4 So, 51-17-11+4=27
• Do not underestimate the quantitative section specifically if you have a math background.
• Though basic calculations and basic formulas are required to perform well in the quantitative sections but remember that GMAT quantitative section is primarily focused on understanding and analyzing the questions properly.
• Please make sure that you revise the basics and practice enough before u start taking timed tests.
• Under all conditions please go through the books or material designed specifically for GMAT.
• The CAT format of the test does not allow you to skip. If you find yourself wasting time on a particular question; eliminate as much as you can, make the best guess and proceed. It is okay to guess on one or two question – particularly if it’s a killer question.
• Beware of deceptive answer choice. There will definitely be one or two trap answer choices, make sure you double check on question, which seems difficult.
• Avoid using calculator while practicing as you would not be allowed to use one in the test.
