Hello,
The main cources for becoming a Data Scientist after 12th is B.Tech/B.E. or M.Tech/ M.E. degrees. However, in order to be eligible for such degrees, you must take a non medical stream such as PCM (Physics, Chemistry and Maths) or you can also take an optional subject as computers as it will help to make your base stronger for further courses.
There is no such stream as electronic in class 11th. Hence, you should go for PCM.
I hope this helps,
All the best
