No matter what you study, of course you are an apprentice. I have practical experience when I study directly, but what I learn in school is mostly theoretical knowledge. When you leave school, you need to practice slowly before you can officially take up your post.

Of course, it is also beneficial to study at school for a while before becoming an apprentice. At least the theoretical knowledge has been learned, and it is much more convenient during the apprenticeship, because you don't know anything without learning. If you are an apprentice, I will face you without telling you what to do.

I suggest reading relevant books first, then collecting relevant information online, and then going directly to find an apprentice for a week or half a month. At this time, I know what I want to learn, and then I choose a crash course, so that I know where I need to learn most.
