Hi ! Yes, you can update your engineering stream in 2nd on the basis of some terms and conditions which varies from college to college. Well, in every college there are some basic similarity. First of them is that you have to acquire high sgpa on your batch or of your stream or of your section. It requires minimum of 9.6 sgpa. So hope you understand and best of luck to you.

Hello,
Yes one has full right to shift or exchange his /her course in the 2nd year.

There are some conditions that one needs to follow to shift or exchange the course.

• One should qualify or pass the first year with no back logs.
• One should not be debarred in the previous year.

If all these conditions are followed then one is capable of taking up or shift the course in the 2nd year.
But all these conditions are only followed up in the private universities and colleges not in the government colleges.
I hope this would help you. For further queries please feel free to write me down in the comment box.
