Computers & IT (Non-Engg)

BCA is a job oriented degree course and you can go for job immediately after BCA in Small and Medium size IT companies. Unfortunately Indian IT industry does not prefer BCA for entry level Developer and Testers role. You may get junior developer or Application support jobs. B.Sc CS is a more academic course, and focuses mainly on mathematical and theoretical foundations of computing and help students to become Systems Developers.
Syllabus of B.Sc CS and BCA is similar up to 70 to 80% in various universities. Courses on Computer languages, data structure, databases, and networking etc are common. BCA degree course program is primarily focused on in the field of Computer Applications such as mobile computing, ERP, SCM etc whereas B.Sc CS degree program primarily focused on subjects with more mathematical and theoretical foundations of computing rather than emphasizing specific technologies. It covers all emerging topic like Artificial Intelligence, BIDW etc. Market acceptance of both degrees are similar. Both degrees can only help you to get only entry level jobs and will require acquisition of PG degrees such as MCA and M.Sc IT/CS for a meaningful career. If there are no personal conditions, you are advised to complete MCA or M.Sc CS/IT before seeking a job in IT industry. MCA and M.Sc CS/IT graduates are treated on par with B.Tech CS and B.Sc IT grads for Application development and Maintenance jobs.

PGDCA is only advisable if you aim for a career in IT industry. Also you should pursue MCA after the PG Diploma in order to enhance career opportunities.
