GRE is an adaptive test, and the second section will be adjusted according to the answers of the candidates in the first section. Generally speaking, the specific adaptation situation is as follows: if section 1 is above 13, enter the hard mode, and keep score 156 (it is not a problem for China students to enter the hard mode); Section 1 made 6- 10 mistakes, and entered the middle level. The score is generally150-155; Section 1 error 10 or above, enter the relaxed mode, and score below 150.

Criteria 1: section 1 all right +section2 wrong 1 = 170- > If you have a wrong question, you can still get full marks!

Standard 2:Section 1 error 2+section2 error 2= 168.

Standard 3:Section 1 error 2+section2 error 3= 166.

Rule 4:Section 1 wrong 4+Section2 wrong 5= 163.

In fact, it can be seen that the fault tolerance rate of GRE mathematics is 1-2 questions (or maybe I happen to be lucky), that is, the final score = 170- wrong questions+1/2.
