Hello Banani,

Thanks for contacting Careers360.

No, you can not change your branch in 3rd year of engineering. Branch can be changed after the completion of 1st year only. But after your 2nd year you have to continue with whatever branch you are studying in. So, you have to continue with mechanical engineering.

Hope this helps. Good luck!
