Well, the emphasis varies from place to place every year, but the basic pattern is the same. Just do a comprehensive (junior high school mathematics) problem (you will get proper limit if you do so many papers before the middle school entrance examination, and you will successfully answer the questions during the middle school entrance examination). Briefly introduce:

Radio priority

Simple operations such as fractional operation, rational number addition and subtraction, and absolute value.

, countdown

Second ways

short-lived

The third road

Science and technology law

Next may be factorization, function, triangle, polygon, view, law, garden and so on. But as long as you usually do more questions, it's nothing.

But the last multiple-choice question will be a little more difficult, and there is also the last fill-in-the-blank question, which is generally not repeated for a knowledge point.

answer the question

Equation (simple), probability statistics (simple), trigonometric function, circle (maybe a little bit difficult), and some law inference problems, that is, there are three paths, from simple to complex, it must be noted that solving three problems is often related to 1, 2 problems.

Finally, the last question (function, polygon combination), this short answer is very simple, two short answers can be solved with a little thinking, and three short answers are more difficult.
