in my opinion

Chemistry and mathematics are relatively difficult.

Physics is much better.

Students in our class feel the same way.

Mathematics is more difficult to calculate.

There are too many chemical concepts.

Physics can almost do it right as long as it knows the method.

Physics should have a solid foundation.

From the perspective of winning the prize, it depends on which science you are better, not which one is more difficult. Because if it's easy for everyone, you still have no advantage. If it is difficult, it is difficult for everyone, and the same is true. I used to take part in competitions, but it was more difficult and easier to win prizes. At this time, it depends on who can get 2 or 3 points more from cleverness. You should choose what you learn best. Find some past papers for reference, and you can grasp the level of the topic. Wish you success! ! ! ! ! !

Judging from the span of teaching materials, the span of mathematics and physics is greater than that of chemistry. Feel that physics is more flexible.

The chemistry span is relatively small, and the junior high school chemistry content is few and simple, so it is best to preview. You can win prizes by doing more competition questions, unlike math and physics. I think some aspects of mathematics and physics depend on talent. Chemistry can win prizes as long as it is carefully prepared and has enough questions and understanding. If it is the first prize, you have to work hard.
