BFA

You need to visit the college for the same or request for the application by the college officials.
The eligibility is you must have passed Higher Secondary/Intermediate (10+2) any other examination recognized as equivalent thereto, shall be eligible for the course.

I believe there is some age limit for pursuing Bachelors, yet you can confirm from the institute where you wish to apply. You may be in luck and get admission.

Firstly, decide on the college where you wish to take admission. Thereafter, fill their application form but before fill the form do check the eligibility of the desired college.

Hello Urgyan,
I would suggest you to contact the college through the contact details available online. Talk to them and get a clear information on the entire admission process. It would be great if you visit the campus in person so that you can see the college and reviews from the students there.
I hope I have answered your question. Please comment below if your query is not answered yet.
