GRE revised General Test: Khan Academy Free Test Preparation

As you prepare for the Quantitative Reasoning measure of the GRE^® revised General Test, we want you to be aware of another free resource that may be helpful to you. Using instructional videos, the Khan Academy website provides additional explanations of concepts in the Math Review for the Quantitative Reasoning Measure of the GRE revised General Test.

For each topic in the Math Review, the table below provides links to relevant sections on the Khan Academy website that contain instructional videos on the topic. Note that some videos in the referenced sections may contain content that does not appear on the GRE Quantitative Reasoning measure. For example, the group of videos labeled "GEOMETRY: Right triangles and trigonometry" contains videos involving trigonometry, which does not appear on the measure.

ETS is not responsible for content on the Khan Academy website; if you experience difficulties when viewing the videos, visit the Khan Academy Help Center to troubleshoot or report a problem.
