Hey Nasir,
Admission process for MCA course might be different for every university but generally universities keep that at 60% in your graduation. Moreover coming to some good colleges you can opt for central universities like AMU, Jamia etc. Also there are private universities which offer quality education and practical exposure to the students.

BCA and BCS are similar degree with difference in few electives only. BCA has more emphasis on Computer Applications development . BCS emphasis is on Computer Organisation thus graduates will have more understanding on internals of computer architecture and computation theory. BCA is common degree with wider acceptance in IT industry.

Both BBA and BCA have good career opportunities. BCA graduates can be employed in IT companies and internal IT department of Business enterprises. However BBA graduates can be employed in all types of industries. Thus opportunities for BBA graduates is little better. Also BBA can do MBA to improve career prospectus.

If you believe in yourself you can go for these courses. Some good universities to suggest
