Obedience classes serve a number of purposes.

You will be the trainer of your dog. The classes are actually for you.

Your trainer will teach you things about reading your dogs body language. He/She will teach you things about what YOUR body language means to your pup.
You will learn how to get and keep your pups attention and how to make "training" fun for your pup.
All excersices will be broken down into age appropriate pieces that allow you to always "succeed". The bond you build with your pup working like this will set you up for other things you may want to do together in the future.
You and your pup will also have the benefit of watching all others in the class receive instruction. Your pup will be around other dogs and people which is an important addition to the huge amount of socializion your going to be doing anyway.
Just the relationship you build with your pup through the experiences you have in a class will be worth going.
Good luck with your new puppy. Enjoy.
