It usually takes 3-9 months, but the longer you study, the more baking categories you learn and the better you learn. However, when choosing a professional school, you can pay attention to it from the aspects of teachers, teaching products and school strength.
Self-study usually takes one day to one week to learn a variety. If you are interested in studying at home, buying baking materials, baking tools and ovens is not a small expense, and learning to make cookies or cakes may not be successful at one time. Therefore, if you take the self-study exam, you can sign up for a short-term crash course, which can save a lot of detours.
If the purpose is to open a store, it is recommended to study for about 9 months and learn more categories so that the products in the store can be innovated from time to time. It should take 2-3 months to prepare for opening the store, confirm the decoration and sell the products. If you go to a professional school, some schools will have employment creation policies and will always help you open a shop, so the process of opening a shop is clear, so it will probably take 1 year!
