Is GarageBand a prerequisite?

Hi all,

I was just wondering, do you need to be a fluent Garageband user in order to progress quickly onto logic? Would using Garageband first provide me with the necessary know-how of how to go about using the logic interface. I'm just asking because I have garageband but would like to buy logic studio as well, so shal i just cut out the middle man?

Cheers,
Jamesy

No. I've played with GB only a tiny little bit. I did have previous experience with cubase.
