1, reason:

The topic involves a wide range of knowledge points, requiring candidates to fully grasp the relevant knowledge points of Mathematics I and be able to use them flexibly.

② The calculation amount and complexity of the test questions are high, which requires candidates to have strong calculation ability and patience.

(3) The thinking and methods of solving problems are flexible, which requires candidates to have innovative thinking and problem-solving ability.

(4) The examination questions have a high degree of discrimination, which can well test the mathematical level and ability of candidates.

2. Mathematics 1:

Mathematics 1 usually refers to the first mathematics course or examination subject in some disciplines or examinations, and the specific content and difficulty vary with different disciplines and examinations. For example, in China's higher education, mathematics may refer to the first course of college mathematics, including advanced mathematics, linear algebra, probability theory and mathematical statistics, which is one of the important basic courses required by science and engineering students.

The difference between Math I and Math II;

1, content and difficulty difference:

Mathematics 1 usually involves a wider range of contents and is relatively more difficult. It may include advanced mathematics, linear algebra, probability theory and mathematical statistics. Students are required to have a deep understanding and mastery of various knowledge points. In contrast, the content of Math II may be relatively simplified, less difficult, and more focused on the examination of basic knowledge and skills.

2, the application direction is different:

Math 1 and Math 2 are also different in application direction. Mathematics one pays more attention to theory and abstraction, emphasizes the derivation and proof of mathematical principles, and cultivates students' logical thinking ability and mathematical analysis ability. Mathematics 2 pays more attention to practicality and application, emphasizes the application of mathematical knowledge in practical problems, and cultivates students' mathematical modeling ability and practical problem solving ability.

3, test requirements and test questions set:

Math 1 and Math 2 are also different in test requirements and questions. Because of the difficulty of math 1, its examination requirements are usually strict, which requires students to have a deep understanding of various knowledge points and flexible application ability.

In the setting of topics, Math I may include more proof questions and complicated calculation questions to test students' high-level math ability. The examination requirements of Math II are relatively relaxed, and more attention is paid to the examination of basic knowledge. In the setting of topics, Math II may include more basic questions such as multiple-choice questions and calculation questions to test students' mathematical foundation.
