hey ,

Both the courses are equally good. BCA deals mostly with computer applications focusing on applications like ERP, database, web, etc. The main focus of BCS is on fundamentals of computer science including both hardware and software. You can go for MCA or MS-IT after both the courses.

You can check the syllabus of both the courses that will help you to know about them in detail.

Dear student

Both of the courses are similar. Check the  syllabus for the both. The one which teaches the latest programming tools , the better.

In terms of degree BCA seems to be more important and you can follow it with an MCA.

BCA is more practical then B.sc so its on you want you want to learn more theory go with b.sc and wanted to have practical knowledge then choose BCA

Hope this helps

All the best!!!
