  • Geometry 
  • Data analysis

Quantitative Comparison Overview

  • Always first 7-10 questions in a computer delivered GRE 
  • Four static choices for every problem
    • A | quantity a is > quantity b ALWAYS
    • B | quantity b is > quantity a ALWAYS
    • C | quantity a is = quantity b ALWAYS
    • D | there is no consistent relationship between the quantities 
  • Average of < 1:30 minutes per problem
    • Average for quantitative section is ~1:45
  • Always aggressively attempt to at least logically eliminate choices for every quantitative comparison first in section

Sample Question 

1) Set up scratch pad, quantities first 

  • Articulate the information as mathematical as possible 
  • List choices in center for process of elimination assistance 
  • Place any root conditions for problem above the choices/quantities 

2) Do I want to plug in?

  • No: evaluate conditions and quantities as mathematically as possible to determine if there's a consistent relationship or if consistent relationship cannot be determined 
    • Immediately eliminate choice D if no variables provided in problem
  • Yes: First plug in an easy value or values to determine one possible outcome for the quantities to eliminate two of A, B, or C
    • Easy values: 2, 10, 100 or 1/2

3) Plugging in Only - Strategically retest additional values to determine if the original outcome is the only possible outcome using FROZEN checklist

  • As soon as a different outcome is produced, select D
  • If a second equivalent outcome is produced, select C
  • Must test at least two allowed FROZEN values before selecting either a or b 

FROZEN Checklist 

  • Fractions
  • Repeats
  • One
  • Zero
  • Extremes 
  • Negatives
