The arithmetic concept tested on GRE is extremely simple. Many
primary school students can do it! It covers the following topics:
1. Integers & Number Theory
5. Ratio and Proportion
6. Exponents & Roots
8. Permutation and Combination
11. Standard Deviation
Among the above 11 sections, the last three are
a little difficult, especially the Probability. You should do more
practices so that you won't meet problems on the test day.
On the test day, you are required to complete 14 Problem Solving
questions, and 14 Quantitative Comparison questions in 45 minutes.
