Dear student,

Hello there, I hope you are doing well.

See for bachelor in computer Applications, students from commerce, arts, and science are free to study bca. It's not necessary you should study maths or computer. Some colleges do prefer their students to be from science or with background in maths or computer science. So you will have to choose a college that doesn't follow this rule.

Some colleges conduct a small entrance test to admit students while others admit based of merit earned in 12th class.

The basic requirements is that you must know English.

In bca you will learn maths as computer and maths are interlinked and they go hand in hand.

Hope this helps.
