If you want to improve the speed of solving problems, you must lay a good foundation, and an empty shelf is easy to fall. I think the math difficulty of managing the entrance exam is ok. Take your time, the exam is nothing more than laying the foundation. (1) Master the basics; 2 do more questions.

The reasons for the slow speed of doing problems are nothing more than the following:

(1) Unfamiliar with the question type: There are probably three reasons for unfamiliarity with the question type: unfamiliarity with the knowledge point itself, unfamiliarity with the thinking of solving problems (unfamiliarity with thinking), and insufficient analysis of the question type.

(2) Insufficient ability to do problems: insufficient computing ability, slow reading speed and insufficient ability to accept information.

(3) The method of solving problems is not simple.

(4) The thinking of doing the problem is not wide.

In the usual review exercises, we should do the following:

1. Think more and pay more attention to skills: try to reduce rote calculation, increase the proportion of thinking, put thinking and skills first, make full use of the hints between topics and options, calculate more and do less, use more brains and do less.

Because they are all multiple-choice questions in the joint entrance examination, we should use some skills, such as the substitution of special values, the substitution of options, and the exclusion method (option inversion) to minimize the dead reckoning from beginning to end.

2. Clever calculation and reanalysis

In the process of doing problems, we should follow the principle of "calculating skillfully and analyzing more" and increase the proportion of understanding, analysis and judgment. We should not only pay attention to analyzing the obvious known conditions given in the problem, but also find out the hidden known conditions in the problem, correctly understand and comprehensively analyze them, and really improve the speed of solving problems.

3. Good induction, heavy summary

Although there are many knowledge points in the entrance examination, according to the summary of the real questions in previous years, you will find that the proposition preference is clear and many test sites appear repeatedly. You must keep these questions in mind, and learn to transform the real questions into propositions by yourself, so that you can face them easily in the examination room.
