No, according to the latest information available for the 2024 admissions cycle,  mathematics is not compulsory for a BCA program at the Ambedkar Institute of Technology (AIT) Delhi. You need to have secured at least 50% aggregate marks in your 10+2 examination from a recognized board. While the specific subjects in your 10+2 aren't explicitly mentioned as a requirement, an arts background shouldn't hinder your eligibility as long as you meet the minimum marks criteria.
