I am a freshman majoring in polymer materials and engineering. What is the main study direction of this major, how do I learn it, and what do I learn?

No best answer

1. Learning direction: Polymer includes plastic, rubber and fiber. The polymer major of my school is subdivided into three directions: synthesis, processing, and biomedicine.

2. Learning content: Freshman and sophomore study basic courses include advanced mathematics, college physics, chemistry courses (university chemistry, modern chemistry foundation, chemical engineering principles, etc.), related physics/chemical experiment courses, mechanical courses (mechanical drawing, machinery) Principles, mechanical design, etc.); from the second semester of the sophomore year, learn professional courses, including polymer chemistry, polymer physics, chemical fiber, plastic molding technology, rubber molding processing basics, etc.

3. Learning method: listening to lectures in class combined with after-class exercises, studying well + combining theory with practice, think about relevant theoretical knowledge when doing experiments, consolidate + establish a framework of knowledge, and be systematic
