Yeah, in college I ended up doing a few group projects myself. At least when it was allowed. I did fail a class because group work was mandatory. It usually happened due to me not getting up and finding a group when it was time to form groups. Sometimes I would get up and walk out of the class when group forming time came around. Then the teacher would eventually mention to me that I wasn't in a group and try to put me in one. A few times the teacher looked at me like I was crazy when I asked to do my own project. I guess I would rather have one instance of anxiety by presenting the project in front of the class as opposed to multiple instances of anxiety by meeting with the group and still having to present in front of the class.
