Hi Sandip,

For a candidate to take admission in any course under B.Tech. at Heritage Institute of Technology, Kolkata, he/she needs to give JEE Maon or WBJEE examination. If you have given any of these, then just sit back and wait for the counseling to start. This starts generally in the month of June or July. Keep surfing and checking for the updates. Here's the link to their official site:

Good luck!
