To be eligible for a BCA (Bachelor of Computer Applications) degree, students typically need to have completed their 10+2 (or equivalent) from a recognized board, with a minimum aggregate score of 50-60%. While some institutions may require Mathematics or Computer Science as a core subject, it's not a universal requirement. Most universities also do not have a strict upper age limit for BCA admissions, though some may have a minimum age requirement, often around 17 years old. Some colleges may also conduct entrance exams to assess a candidate's aptitude in areas like English, Maths, and Logical Reasoning.
