The difference between those who have studied olympiad and those who have not.

First, the ability to take exams is different.

The test-taking ability of learning Olympic Mathematics is much stronger than that of not learning Olympic Mathematics. In our country, Olympiad Education is actually a "stale" Olympiad Education. Everything is for exams, that is, solving some difficult and strange math problems with the method of Olympic Mathematics can improve the ability to take exams and is of great help to exams. However, if you don't learn Olympic Mathematics, you should solve problems according to universal laws. It is better to learn Olympic Mathematics.

Second, learning interests are different.

Learning olympiad has low interest in learning, but not learning olympiad, but high interest in learning. The reason why Olympiad is no longer a plus item in the college entrance examination is because Olympiad has largely buried children's interest in learning. Because the Olympiad pays attention to being unconventional and strange, it is contrary to the routine in problem-solving skills. In a sense, saying "yes" as "no" is counterproductive in cultivating children's interest in learning. Therefore, after learning the Olympic Mathematics, their interest in learning is low, but they are not interested in learning the Olympic Mathematics.

Third, the training cost is different.

Learning olympiad requires more learning costs, while not learning olympiad requires more learning costs. Generally speaking, Olympic Mathematics is a training course, which costs a lot of money and tens of thousands of dollars. If you don't learn Olympic Mathematics, you can avoid spending these expenses. Therefore, in most working-class people, it is not suitable to encourage children to learn Olympic Mathematics. It costs a lot and can't get the reward it deserves. It can be described as "losing the wife and folding the soldiers."

In addition, there are other differences between learning Olympic Mathematics and not learning Olympic Mathematics, including academic performance, learning thinking and so on. Generally speaking, there is a clear difference between learning Olympiad and not learning Olympiad.
