Hello,
Bachelors of Computer Applications is a 3 year uundergraduate course offered by many colleges in India. It's great for those interested in IT. Even if you studied commerce in 12th grade, you can still pursue BCA. Eligibility requirements may vary between colleges. Some universities may require maths or computer science for admission but the most of the colleges offer admission for any stream so you don't need to worry about that. You can check the eligibility criteria for the college you are looking for to confirm or provide me with the college name so I can give you the correct answer.
I hope this helps,
Thank you
