Hello Student

It will be better for you to do data science course after passing B tech electrical at least with 60% marks.there is no such courses which will satisfy  your interest of doing Mtech electrical after gate qualifying and PG diploma in data science at  the same time. So if you are interested in data science course you can do after qualifying in GATE examination and do Mtech in data science. It is not a matter from the branches of Engineering you have done BTech.you can do Mtech in data science after qualifying in in GATE examination and score at least 60% marks in BTech any of the streams of Engineering ..

Hope this helps.
