one more piece of advice,
please don't take part in competitions expecting a "must win" kind of thing, or after that cry foul.
every competition is subjective, even if you are good, you can't win all the time; even if you are bad, sometimes also might win, that is life.
this is not targeting anyone in particular, but you can read it to gain insights on what the wrong attitude when participating in competitions can lead to.. winning is not everything.
