DEAR ASPIRANT,

• Students who have done their graduation in any discipline like Science, Commerce, Arts, Engineering, BCA from any recognized university are eligible to apply for this course.
• Aspirants should have studied Mathematics subject in the 10+2 standard or graduation level.
• The qualifying examination must be passed with 50% marks (45% for SC/ST category candidates).

As you have BCA degree its possible to do MCA though you were Bipc student.

hope it helped.
