Hey!There

If you want change in stream in same College in which you are studying right now,then you can't change your stream and if possible then you can change stream after 1sy year and swapping will be based on your 1st semester results...Branch swapping facilities is not available in every College and for biomedical engineering nothing can be said..So it will be better for you if you will change College and take admission in other stream whatever you want...

Ask if any query..

GOOD LUCK!
