GRE Math Quantitative Comparisons

Quantitative Comparison questions require much less calculation than standard problem solving. These questions account for approximately 35% of the GRE quantitative reasoning section. You should not take more than one minute for each problem. Do not do unnecessary calculations: compare rather than calculate.

Each test has ten questions and should take 10 minutes.

Remember that variables (x, y etc.) can be positive, negative, zero or fractions, unless the question states otherwise. So consider all the options before deciding the relationship.
Read our explanations carefully and learn from your mistakes.
