Hello ,
There are so many courses you can do after passing class 12 with science stream but choosing the best one will be hard as every person have different interest to different courses but if we see according to popularity it will be BTech as millions of students every year choose to pursue Engineering courses (Civil , Computer science , mechanical Engineering etc ) as it provides good placement to the graduates .
Another famous course is MBBS which is the first preference of most of the medical students (PCB) .
So you should choose the course in which you have interest and you can see yourself becoming a professional in it .
Hope this helps.
