Whether you can win the prize in the competition can't be based on your usual achievements. The key depends on whether you are interested in the problem.

In junior high school, none of my classmates who usually study better than me won this award.

Pay attention to where your usual problems usually appear, such as quadratic function, circle and trigonometric function. These topics close to the high school textbooks are the easiest to give questions, especially the complex questions of circles, triangles, trigonometric functions and quadratic functions are the easiest to appear in the last question.

Comparatively speaking, these topics are not the main topics for scoring. The key is that the previous multiple-choice questions and fill-in-the-blank questions are particularly easy to get points, and the latter questions are mainly used to widen the gap, so when doing the questions, we must first firmly grasp the previous questions and leave the questions that we don't understand to the end.

Preparation is to buy 1-2 math contest materials, and it should be the kind with examples. Look at the above problem-solving ideas more, and then do the following exercises slowly. Then, if you have time, do the following questions according to the standards of the competition and set a time for yourself.

There will be things you can't do at first, but don't lose heart. Think of it as your own interest, and your math level will improve slowly.

In recent years, the integer root problem of quadratic equation with one variable is a necessary test point.
