Same for me. Bullet seems to be tougher than rapid.
bullet tips?

Bullet games often feature recurring tactical motifs and patterns. Study common tactics such as forks, pins, skewers and discovered attacks, and practice recognizing them quickly during your games.

Don't get upset at bad moves or blunders. Keep making moves even if they aren't optimal. Even if you make an unintentional move, keep playing as if you meant that move. The fewer pieces you have the less opportunity there is to blunder. The more pieces your opponent has the more opportunity they have to blunder. Have a simple game plan, pre-move often, even if you get cheesed in the opening. Remember the only way to win is by checkmate or on time. Even if you are at a major material disadvantage you still can win. Conversely you can have a major material advantage and still lose.
i want to get my bullet rating same as rapid but it is very hard.
