BCA (Bachelor of Computer Applications) admissions typically begin between April and June each year, depending on the university or college. Most institutions open their application portals after the Class 12 board results are declared. Some universities conduct entrance exams, while others offer merit-based admission. It's important to regularly check the official websites of preferred colleges for specific dates, eligibility criteria, and application procedures. Early preparation and timely application submission are crucial, as deadlines may vary across institutions.
