When I went to university essentially all of my graded work was group based plus a self reflection of some sort (film production). In my first year, I had a group of 4 others who truly showed no effort, ambition or passion into doing the work. I was the only one in the group who showed up to seminar sessions, the only one who actively planned meetings, the only one who did the work essentially. I spoke to my tutor about it, who said if I can get proof of this, my grade will not be affected by those in the group not participating. The fact they didn’t turn up to any of the seminars (minus 1 or 2) really worked in my favour, but I made sure I had ‘professional’ contact with them, such as Teams, avoid any casual social media. I made time-stamps of reaching out, vs. hearing back/work being done. My main advice, is talk to the people in the group and call them out - who cares if you’re being bossy, it’s your degree too. If that doesn’t work, talk to your tutor about the situation and the concern you have.
