The only thing he did was that he did not study for the sake of scoring well. He studied because he loved it. So you don’t need to worry about your scores, just give your best. Secondly.

If you have a pessimistic attitude then nothing is going to work out. Just always keep in mind that THERE IS ALWAYS A WAY OUT.
