Stenographers mainly test practical operation and written test, which is the content of some theories. The actual operation is that the stenographer's typing speed on the computer is 140, which is enough. It is useless for stenographers to take the advanced exam. Stenographers learn too slowly. There are specialized stenographers. I bought it in Harbin Fuxing Education, which is a place for training stenographers. You can still attend classes if you buy a machine. Even the teaching materials and software are installed.
