How do you become good at drop games in Maplestory

Have a fast computer and drop game with people you know and will gb(give back).
I know some tricks in Fm drop game
1. Ladder trick = Drop at the very bottom of the ladder and hold z. Don't spam z, just hold it down.
2. Sitting trick = Sit down and when the opponent gets confused and moves away, drop and hold ZERO!! NOT Z!
I hope these help.
