When doing a comprehensive question, you should understand what this question is about and then establish the direction. As for what can be examined, we can start with the answers and conditions. The general questions will be clear. For example, if there is a key point, we should consider the center line.
If it is a comprehensive problem of graphics, it is suggested to draw a standard diagram for the difficult problem and then infer the answer according to the standard diagram, thus establishing the direction. If it is an algebra problem, you should list and analyze all the conditions you think of according to the conditions in the problem.
The questions in junior high school are not so difficult to calculate, so the answers are generally special, which is also a push in the direction.
5. Practice more questions, that is, do more questions but pay attention to summary, such as what is the answer analysis of such questions, what do you think, and what do I think. To do a question, we should sum up the problems in our own thinking process and the ways to find the answer to this question. Try to use as many methods as possible for a problem. If you do a function problem that is troublesome, try to solve it in another way and I will help you next time.
There is also division analysis, and then synthesis. The comprehensive question is to put a lot of things together for examination. This junior high school is not deep enough, but in senior high school, especially in science physics problems, the linear motion of magnetic field, electric field and gravity field with uniform curve will be combined into one problem, requiring every simple aspect.
