What do English magic schools teach? Is it really teaching magic?

Magic is actually taught by divination, alchemy and witchcraft.

I used to believe in science, but now I feel that science has great limitations, especially the judgment that the universe is made up of matter is too arbitrary. Although the scientific conclusion must be correct, it is by no means the whole universe. Now I believe there is magic in the world. I've been studying witchcraft recently. There are many magic schools in Britain, but I don't think they are as wonderful as Harry Potter.
