Hello my friend.!
At first I congratulate you for choosing biomedical engineering as your career. Generally after you get your rank card, there will be a delay of some days for counselling. So try to look after the news regularly. And the most important thing is to check the official website that deals with EAMCET in your respective states. In some cases, there will also be some states where they issue/send messages regarding the information required. So don't worry and check news daily
