No, computer science is not compulsory for BCA (Bachelor of Computer Applications) if you are a commerce student with maths in class 11. Many universities and colleges offering BCA programs accept students from any stream (Science, Commerce, or Arts)  as long as they meet the minimum eligibility criteria, which typically involves:

• Passing 12th standard from a recognized board.
  
  
• Minimum marks requirement (often around 50%) with Mathematics as a subject in some cases .
  
  Having a computer science background in class 11 might be helpful as it would give you a head start with some basic computer concepts. However, it's not mandatory for admission to most BCA programs.
  
  I hope it helps!
