Greetings!

For becoming a data scientist,you should opt for CSE ime. Computer science engineering , IT- information technology or ECE- electronic and communication engineering. These all three courses will help you become data scientist. Some colleges like NSUT, Delhi also provide a special branch which deals with only data scientist role ,you can opt for that also. I wouldn't suggest you to opt for maths and commuting for becoming a data scientist as that branch deals with other specialistation.
