So in the recent contests and tests, I felt that I lost more points by making silly mistakes. I feel that increasing my ability to focus will help me improve.

But how to do so???

• I tried high-intensity exercises before 1-1.5 hrs of a contest (doesn't seem to help at all).
• I have tried to follow a good sleep schedule (helps but I failed miserably to follow it for more than 2 days).

So I wanted to ask about the practices you people use while practicing and before a contest.

Thanks!!
