Which course is better among BCA and B.Tech (IT)?

Both are based on your choices. It depends on individual interest. If there is a conflict between BCA and B.Tech, then my suggestion would be to go for B.Tech in IT because it is more popular and there is more chances of grabbing better opportunities. Good luck.

Dear, BCA is 3-year duration professional course in IT whereas B.Tech is 4-years engineering degree course in IT. B.Tech in IT is always better as Indian IT industry prefers B.Tech much more in terms of placement and gives them better pay scale and position.
