The first is the previous apprentice, who went directly to the bakery to study.
The second is to study in a professional training school.
The advantage of studying in a bakery is that you can intuitively feel the operation mode of the store and understand the basic things in the industry. And I'm still getting paid during my study. However, the learning cycle may be longer. Being an apprentice is actually helping the master do other chores. If you really want to learn something, it is impossible for the teacher to teach you seriously. Of course, if you meet a more responsible teacher, you may be guided, but most of the time is wasted on other things.
Therefore, it is best to choose a training school, choose a large-scale professional school, and inspect the school environment, teaching situation, teacher level and so on.
