I know that I don't cut well in the company of others. Also I want to listen to my MP3 player at times in order to focus on other than all the chatter, even though I know the chatter is helpful.
Perhaps having a friend who understands your work mode go with you would be a big help. She could let you know when to pay attention.
Also, if like me you don't cut well in the company of others, ask the presenter/teacher for cutting directions before hand after explaining this to her. I always promise not to reveal to others what she tells me about the cutting. It has worked so far.
