202 1 It is difficult to take the postgraduate entrance examination in mathematics. From the perspective of multiple-choice questions, the proportion of multiple-choice questions has increased, and the big questions have decreased. Not too big questions may lead to higher comprehensiveness, especially line generation and probability. It is often more difficult to combine two big questions into a big question with a score of 1 road 15 and integrate multiple knowledge points.

This year's postgraduate entrance examination politics is closely related to major events and important speeches at home and abroad. The proposition angle is quite satisfactory, and there is no particularly strange or difficult angle, so the overall difficulty is not great.

Postgraduates' skills of taking exams in mathematics

First, the reverse push skills

The literal consciousness of reverse deduction technology is also called reverse substitution technology. When you can't find the answer, you can reverse substitute the option into a known item. If it conflicts with the condition, it is the wrong option, and vice versa.

Second, direct push skills

Direct deduction is also a common skill in our exams. According to the known terms and conditions given by the stem, according to mathematical knowledge and related formulas, the answer is deduced and analyzed. This method is the main test method in our exam, and it is generally used to answer calculation questions.
