hi,

see btech in computer science course give you overall India of the software engineering, AL and soft computing, numerical, data science, discreet mathematics, however to get a precise course knowledge you have to take courses on different technologies from coaching or online platform. however it also give to time to choose which course interest you the best since there is various technologies.

on the other hand btech cse with specialization of data science gives you major course work only in data science. however there is decent jobs available on data science field.

so it depends on you which course you may go for. however the specialization course is quite new in galgotia, but as per the previous placements records cse stream has decent placement among other streams.
