• Comparison
• Multiple Choice - one answer
• Multiple Choice - multiple answers
• Numeric entry/Fill in the blanks.
You can use basic calculator and basic calculator is provided on the screen.

### Quantitative TIPS

Format of GRE quantitative Section

Mathematical comparisons 14*
Problem Solving 10*
Chart 4*

Be Cool! Its very important for quantitative section. Prepare well on Mode ,Median, Probability, Permutations, Combinations. You may be getting around 4 questions on above topics.

We are listing some TIPS.

• 0 is not prime number.
• 1 is not prime number.
• 2 is prime number.
• If |a| < 2, then -2 < a < 2; if |a| > 2, then a > 2 or x < -2.
• Total degrees in a polygon=180(n-2), n is number of sides.
• probability =(Result you are looking)/(Total results).
• n!(n factorial)=n*(n-1)*(n-2)*...1
• Permutations is arrangement of things in definite order. While in Combination order doesn't matter.
• Median is the middle value in a set of numbers above and below it.
Example 1 :Consider G={2,4,7,8,9,12,14}
In this case 8 is median because there lies three other numbers before and after 8.

Example 2 :Consider G={2,4,7,8,9,12}
In this case median will be average of 7 and 8 i.e. 7.5
• Mode is the number or range of numbers in a set that occurs the most frequently.
Example Consider G={1,2,4,8,17,2,4,5,6,7,8,2}
In the above set 2 occurs thrice so this is mode.
• Range is defined as difference between maximum and minimum numbers in a set.
For above set Range is 17-1 i.e. 16.
• Standard Deviation of a set is measure of the set's variation from its mean.
Example Consider two sets G1={3,4,3,4} and G2={10,15,14,16}
Then It can be seen G1 has lower S.D. as compared to G2.

CD Provided by ETS has questions on Mode, median...Practice well!

Good Luck!
