Question about Class skills and multiples of the same skill

[Merellin]

So, This might sound odd, But if you have for example Perform as a class skill (Like if you are playing a Bard) And you pick up Perform String, Perform Sing, And Perform Act, Would you get your +3 class skill bonus on all of them or only on the first one?

Each of the craft, knowledge, perform, and profession options is effectively a separate skill.

In most cases classes give a class skill bonus to all of the craft, perform, and profession 'sub' skills within a category. There are only a few exceptions to that. Knowledge sub skills, on the other hand, often only have a few which are class skills for a given class.

For instance, a Wizard gets the class skill bonus to all knowledge skills... but a Rogue only gets the bonus to Dungeoneering and Local knowledges.
