Breast feeding class

I am attending a breast feeding class at the hospital today and was wondering if anyone else has gone to one?? What should I expect? I am a very shy person and get embarrassed easily so I would like to be as prepared as possible if the class is going to be.... Awkward lol. Yes I know that breast feeding itself is going to have awkward moments but I have had months to mentally prepare for that (I'm sure that it makes sense for some people). Also any suggestions on what would be helpful to bring to class would be good too, thank you!!!
