AB test paper is the so-called "one question and many volumes". By disrupting the arrangement order of the questions in the same set of test papers (question number dislocation method) or the arrangement order of the options in the same question (option dislocation method), the purpose of cracking down on cheating in objective multiple-choice questions is achieved.

(1) title number dislocation method. The topics that don't emphasize the order of difficulty are staggered, which disrupts the order. For example, 1, 2, 3 and 4 multiple-choice questions are sorted according to this question number, and the correct answer options are A, B, C and D respectively; If you sort by 2, 1, 4, and 3, the options for correct answers become B, A, D, and C. Therefore, the answers to the same questions in different papers are completely different.

(2) The options are misplaced. For questions that emphasize the order of difficulty, the answer option dislocation method can be used. For example, the solution of equation 10х+8 = 38 is 3. If the options are staggered into multiple-choice questions, the answer is completely different:

Examination paper 1: a.2b.3c.4d.5 answer: B.

Test paper 2: a.2b.5c.4d.3 Answer: D.

Test paper 3: a.4b.5c.3d.2 Answer: C.

Test paper 4: a.3b.2c.4d.5 answer: a.
