You only need to look at the math on OG to review the questions on machine warp and have certain reading ability. I guarantee you 168+ (China students mainly pay attention to the standard deviation and the expression from pentagon to decagon).

Let's talk about KPLAN, which is a software that pursues bias and strange questions. It has only one purpose, that is, to feel that you know everything, and to beat yourself with it so that you don't despise GRE. My KPLAN V is basically half wrong, and then the test V is 159, so this software is far from the test.
