Can someone tell ways by which I can keep my mind cool during contests? I don't know how this happens that heartbeat increases (rushing through problem statement skipping important points, like if it is asked to print index, I am printing count of operations) , mind loses its calmness and even easy problems like A and B are done wrong.

Even after practicing regularly this problem remains and I think practicing more problems is not the solution to this "contest-anxiety" issue.

Can someone please guide me who have improved upon these psychological things?
