First, psychology has little to do with mathematics. Of course, some numerical calculations are very common, and the content of mathematics is not difficult at all, so don't worry.
Second, psychology is still biased towards liberal arts. It has a certain distance from science, so don't worry too much. Even if there is some science content in it, you can learn it by yourself. It's very simple.
Third, whether liberal arts or other content psychology is more important, it is always necessary to learn. As long as you study, you can overcome difficulties. The process of learning is to overcome one difficulty after another and then become the master of learning. This is not difficult. Dispel these doubts and choose psychology.
Of course, we should also study according to our hobbies, not just simple hobbies. Besides, mathematics may be a bit difficult, so we should face up to the difficulties. We still need to learn some simple math problems. Although mathematics needs genius and talent, we sometimes need to learn and face up to difficulties.
Only by constantly overcoming difficulties can I grow, and it is always so smooth and difficult to succeed. There must be some experiences and lessons. I wish you study hard and make progress every day.
