GRE Quantitative Comparison Questions
Quantitative Comparison questions include two quantities, and asks test takers to select whether quantity A is larger, quantity B is larger, the two are equal or the relationship cannot be determined. These questions always have the same four choices, always in the same order.
If solving the question algebraically or arithmetically would be time consuming, GRE test takers might save time by estimating or plugging in values for variables. The questions can involve algebra, geometry, arithmetic or data analysis concepts. The fourth choice should only be selected if the values of A and B or the relationship between A and B cannot be determined.
