I learned a lot of knowledge and skills about mathematics in the online mathematics class of senior one. This course not only gives me a deeper understanding of mathematics, but also cultivates my ability to solve problems.

In the online class, the teacher explained all kinds of basic knowledge of mathematics, such as algebra, geometry, probability and so on. Through the teacher's explanation, I gradually understood the concept, principle and problem-solving method of mathematics. In the process of learning, I also gradually improved my math skills and abilities through a lot of practice and practice.

In addition to the basic knowledge, the teacher also explained some difficult topics and math competitions. These topics need my careful thinking and analysis. Through the practice of these topics, I not only improved my math level, but also cultivated my thinking ability and problem-solving ability.

In the process of learning, I also encountered some difficulties and challenges. For example, sometimes you will encounter some problems that you don't understand, and you need to think and try repeatedly to find a solution. But through consulting teachers and discussing with classmates, I gradually overcame these difficulties.

Generally speaking, the online math class in senior one helped me a lot. Through the study of this course, I not only mastered the basic knowledge and skills of mathematics, but also cultivated my thinking ability and problem-solving ability. I believe that this knowledge and ability will have a positive impact on my future study and work.
