Mathematics is logical thinking, and biochemistry is abstract and difficult to remember.

Choosing a major depends on what you are good at. If you are similar and don't hate studying biochemistry very much, I suggest you choose biochemistry. After all, it has something to do with your major. If you have something to do with your major, you will be more professional and find a good job. If your math self-study ability is still good, you can consider math if your self-study improves quickly.

Biology is a science that studies the structure, function, occurrence and development of organisms (including plants, animals and microorganisms) and is a part of natural science. The purpose is to clarify and control life activities, transform nature and serve the practice of agriculture, industry and medicine. For thousands of years, human beings have accumulated rich knowledge about plants, animals, microorganisms and human bodies in the practice of agriculture, forestry, animal husbandry, fishing and medicine. From 65438 to 0859, the British naturalist Darwin published The Origin of Species, which established the materialist view of biological evolution and promoted the rapid development of biology.
