How can I follow an apprentice in a film crew?

With your current education, I don't think it's easy to find. After all, it is impossible for the crew to enter the place enthusiastically. If you want to join the circle, I suggest you go to a professional further education school first. If you really have this talent, the teachers in the school will recommend it to you. It will be much better than finding it yourself. Society is cruel, you are still young! Come on!
