What kind of big questions does the college entrance examination focus on?
Everyone summed it up a little differently. One of the biggest problems in mathematics is trigonometric function. Generally speaking, it is 12, which is the same for arts and sciences. The second problem is generally statistical probability, including permutation and combination. Only scientific people can have permutations and combinations. The third problem is generally geometry and conic curves. Then, sequence and derivative function are probably the most difficult in science. Second, the first problem is to solve the triangle, the second problem is probability, the third problem is solid geometry, the fourth problem is conic curve, the fifth problem is series, and finally the derivative. Each problem is about ten.
