There are four types of math questions on the GRE. They are:
The quantitative comparison questions are most likely unlike any you have ever see, and there are several tactics that you should employ when answering them. The multiple choice questions on the math section of the GRE are the standard "word problem" questions that you have most likely seen throughout your schooling. However, there are two types: single answer, in which you select one answer from among five and One or More Answers, in which you select one OR more from a list of choices. Numeric Entry questions are similar to the problem solving questions. However, unlike the other math problems on the GRE where you choose from 4 or 5 provided choices, the numeric entry questions require you to provide the answer to the question using the keyboard -- you input your answer into either a single box or into two boxes if the answer is in the form of a ratio.
The skills that are being tested are the following:
To determine if you have these skills, the questions that you'll see will require you to read and understand mathematical information, interpret quantitative statements and analyze them, draw conclusions, make inferences from charts and graphs, and use math methods to solve numerical problems. The data interpretation questions on the GRE require you to answer questions based on your interpretation of graphical or tabular data. These questions are unique in that in most cases you can approximate your calculations and still arrive at the correct answer -- this is because interpreting graphical data is tricky, and exact values for charts are not always provided.
