Hello Akash simple CS engineering having the subjects such as C,C++,OOPs,DS,Algorithm ,networking etc subjects as normal subjects without any collaboration with the partners such as IBM,etc.Means there significance is less as comparison of CS with IBM collaboration .

CS with IBM collaboration is going to be more interactive as comaprison of normal CS engineering.More practical exposure,certifications,any time learning are other advantages of CS engineering with IBM.

Hope this helps you.If any queries left than comment below.

Thank you.
