Nowadays, bread training classes usually last for about a month. For a novice who has just come into contact with the baking industry, it is not a problem to learn the basics of all bread varieties. Mousse can learn whether it is a cake at room temperature, decoration or tape.
The skills you have learned are not a problem to work in a bakery. A slightly more difficult bread variety requires students with zero foundation to practice more after class. The baker pays attention to practical operation, and there will be no learning problems if he practices more.
Therefore, students with zero foundation must choose schools that pay attention to practical operation. I suggest you go to the school for a field trip before choosing this school.
