Hi Princey,

No!! There is no need of having math as a subject in 12th and you can very easily apply for a BCA course. There is a wide range of institute or universities allow the students to get BCA admissions as a regular subject they passed in 12th class without math as the main subject. But only fewer or say 1 out of 10 asks about the math as a compulsory subject. Most of the universities or institute accepts students of 12th in all streams who have passed their examination with a minimum of 45% to 50% marks. Some universities also conduct an entrance exam for the students on that basis a candidate choose for BCA admissions.

Hope it helps! Comment Down if you have any other queries... Goodluck!
