Should I ditch cl for a group meeting or not?

My group for an English project has 6 people in it and everyone but me has no cles after our 1:00 cl, but I, on the other hand, have one more cl lasting until 2:00...They met without me one time (I had a midterm in cl that day and skipping was just not an option) and I really hate to miss university cles because it costs me about 30 bucks or something for each one and it really is beneficial for me to go seeing as though content from it could be on the exam. I don't have anyone who could lend me notes from it either... I don't want to be a bad group member and not show up for the couple of meetings we have, nor do I want to trust my mark to 5 near strangers.. Do you think I should skip the class, skip the meeting, or inconvenience all 5 other people and ask them to wait around an extra hour for me to finish my class before we meet?
