crappy group

For my grad school class we are required to write three papers with a group. Rewind to the first paper...the rest of my group members dragged their feet as far as dividing the work and turning it into me, the group leader. One member of my group did such crappy work that the other group member and I had to rewrite her section to get the paper in on time. The next paper was seemingly more organized, but someone in my group (not me) plagerized so we're still dealing with the prof regarding that (I was the only person that sited anything in the entire paper). That brings us to the paper that is due on Wednesday. I emailed the group on Wednesday indicating they should pick their sections and have them to me by Sunday night. Here it is, Sunday morning and slacker group member from paper one has not indicated her section....Could I be more frustrated with group work??
In grad school, I think that group work is dumb. Most people in my program are professionals, so most likely have to work in groups in their current jobs. For the record I hate group work and I hate my group.
