I don't know this school, but it sounds like a secondary school. If you study other majors, such as tourism and business, it should be good. I don't know if there is cooking teaching, but there is definitely no bartending major, because there is no independent bartending major in general secondary schools, and even if there is one, it is a professional course. What you have learned is superficial and unprofessional, which is far from professional bartending. If you want to learn professional bartending, you have to go to a special bartending training school. There are such training schools outside. The Horizon Bartender Training School I know specializes in bartending, which is very professional and famous.
