There are 17 Ranks for each Good and Bad class. To level up in each rank, your experience and reputation must be a certain level.
So, in order to get a higher Good rank, you must do good things. And to get a higher Bad rank, you must do bad things like stealing from a star port.
Also note that, shooting yellow players will give you bad experience, and shooting red players will give you good experience.
