Is it difficult to learn pharmacology or accounting?

I am a medical student and I don't know much about accounting. I can talk about pharmacology. Generally speaking, there are many aspects of medical understanding and recitation. If you have a good memory, it is not difficult to learn pharmacology, and students' science is very simple. Don't ask me if it is difficult for students to learn science. I'll tell you to learn anatomy well first. ) So, medicine is the whole series. For accounting, I personally think it should be logical thinking, which will have advantages.

By the way, I happen to have a book on pharmacology at hand, and the catalogue is for your reference.
