1, the first question and the last question, the answer is generally not option A, the first multiple-choice question in mathematics is generally the simplest, and there are many confusing items in the options. Generally, the first option will not be the correct answer, basically in the middle, the last question is the most difficult, and most of the answers will not be the first one, so the later options will be more likely.

3, multiple-choice answers, ABCD is generally evenly distributed. Generally, in the college entrance examination paper, there are 12 math multiple-choice questions and ABCD four options, which are basically equally divided. No more than half of an option in 12 multiple-choice questions. This is basically not the case. The four options are basically 25% each. Students can also get answers according to this law, so as to get answers.
