Is it easy to test the junior certificate of fitter? Shanghai

I took the exam the year before last, and it was not difficult. The exam is divided into two parts: what I should know and what I should know. You know, what I rely on is actually very simple, and I don't need so many review questions. Just take a good look at the after-school questions in the locksmith's textbook you are studying now. I wish I had read more. Mainly concentrated on several points, such as flatness, verticality, angle, such as punching and rubbing.
