**Targeted practice by topic**

At this stage you have taken six practice tests and you probably have a good idea about your weaknesses. To strengthen any specific areas I recommend that you buy the Official GRE Quantitative Reasoning Guide. This guide has a set of 75 practice questions segmented by the following categories: Arithmetic, Algebra, Geometry, and Data Analysis. You can choose to practice selectively on the topics that you find the most challenging or do them all, and subsequently review my video explanations as needed.

**Mixed practice sets**

The GRE Quantitative Reasoning guide also has three sets of 25 practice questions. 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 that students complete each of these three sets in a time of 40 minutes. I have made the time modification based on the computer-delivered GRE General Test where each Quantitative Reasoning section contains 20 questions and you will have 35 minutes to answer them. These practice sets are excellent and are a perfect way to simulate the element of time and pressure of a computer-based GRE test. You can also refer to my video explanations for additional help.
