Dear Aspirant 

Yes definitely you can change your branch after first year of engineering, so for that you need to score better in your semesters and overall results of your first year. If you score more than 80 percent or within top 10 percentile of your branch then you can directly change your branch. 

Good luck for your future :) 

Feel free to ask if you have any further queries. 

Yes Bhargav you can change it but only if you have excelled in your studies of first year then and only you have to asak management about this then they will look after it and you can then change it.But remember you have to do hardwork alot of hardwork.
