Since you’ve completed your 12th from the science stream and later dropped out of BCA, you’re still eligible to explore hotel management courses. For becoming a chef or bartender, you can go for diploma or certificate courses in Hotel Management, Culinary Arts, or Bartending. Many reputed institutes in Mumbai and Navi Mumbai offer such programs like IHM Mumbai, Rizvi College of Hotel Management, and ITM Institute. You don’t need to worry about your BCA dropout, as most of these institutes only require a 12th pass for admission. You can apply directly to their courses through their official websites or walk in inquiries.
