This page organizes all of the 150 video explanations to the questions in the Official GRE Quantitative Reasoning Guide.

**Practice Questions**

The links below provide video explanations to all of the practice questions on each of the four main areas tested on the GRE: Arithmetic, Algebra, Geometry, and Data Analysis.

**Arithmetic**

**Algebra**

**Geometry**

**Data Analysis**

**Mixed Practice Sets**

The links below provide video explanations to the three sets of 25 practice questions in the GRE Quantitative Reasoning guide. Each set is a mixture of content and question types and consists of Quantitative Comparison questions, Multiple-choice questions, Numeric Entry questions, and Data Interpretation set. I would recommend students to complete each of these three sets in a time of 40 minute. This is because these sets are designed to correspond to the paper-delivered GRE general test. I know that most students are taking the computer-delivered GRE General Test where each Quantitative Reasoning section contains 20 questions and you will have 35 minutes to answer them. However, if you can complete these practice sets in 40 minutes, then you should be able to answer 20 questions in 35 minutes. So think of these practice sets as additional practice under time and pressure. To get a more realistic experience of the computer-delivered test, I would recommend taking the free PowerPrep Online test or the paid PowerPrep Plus Online tests.
