You need to make it clear which semester, mid-term, final, simulation or senior high school entrance examination, otherwise you can't interpret it in detail! Now I can only interpret it roughly:

The common questions in the third grade math exam are different in different provinces and cities. Generally speaking, there are mainly:

First, single choice and fill in the blanks: simple application of basic knowledge, error-prone calculation, skill application, law exploration and summary.

Second, answer questions:

1. Calculation: rational number operation, simplified evaluation, equation solving. ...

2. Drawing calculation: ruler drawing, triangle congruence, similarity, symmetry, rotation, Pythagorean theorem. ...

3. Statistics: calculation and analysis of statistical charts, tables, averages, patterns, number of defenders, variance and probability. ...

4. Geometric proof or calculation: triangle, quadrilateral, circle and polygon. ...

5. Calculation and proof of function image: analytical formula, point coordinates, line segment length, closed graph area, inference and guess. ...

6. Solve practical problems with equations or functions: itinerary, profit, project and scheme selection. ...

7. Explore the law, prove and expand the application: the law of graphics, algebra and splicing. ...

8. The comprehensive calculation and analysis of function images prove that the conjecture is expanded and explored by the comprehensive calculation and analysis of quadratic function, linear function and inverse proportional function images. ...
