Personally, I think chemistry should be easier to learn, because I am studying mathematics in college now. College mathematics is a bit difficult, some things are incomprehensible, and there are many contents to learn mathematics. You can go to Baidu to collect it, enter mathematics and applied mathematics, and you can see the content of mathematics. As for the specific chemistry, it is not very clear. I only know that chemistry needs a lot of experiments. If you take the postgraduate entrance examination, I think it is good to study mathematics for postgraduate entrance examination, because mathematics for postgraduate entrance examination is a compulsory subject, and learning mathematics well is one of the key aspects of postgraduate entrance examination.
