To preface this, I’m in math class doing one of those group projects where everyone in the group gets the same sheet and works together to answer the problems. Then the teacher picks a random sheet from that group to grade and bases the entire group grade on that paper.
So obviously it makes the most sense to all get the same answers.

The groups were assigned.

I am definitely not an A+ math student. By far. But I really do try and in this project I was trying to pull my weight. This group was 3 kids besides me who all knew what they were doing far more then me. I eventually get far behind them and start asking for help and then because our time to work on it is almost over, answers. I was genuinely trying really hard to keep up and was not trying to freeload. I just got behind and didn’t want to sacrifice the groups grades and I don’t think they would want to either. I felt bad and repeatedly apologized. 

That should be the end of it right? Apparently not. I don’t follow this person (one of my group members) on Instagram and at this point am glad I don’t. I luckily have a brother who does. He tells me that her story has picture of a black background and some text reading something like “This fucking Grego-o kid, comes into our group and bullshits his way to get a good grade”. 

This kid is semi-popular so their follower count is at about 2k (probably almost all kids from my school) and I’m pretty sure that means a lot of people are going to see it and at this point I’m pissed because I tried as hard as I could to keep up and wouldn’t have copied if I didn’t need to but got called out anyway even after apologizing. AITA if I confront them about this (in person) also knowing I’m not friends with them? Thanks in advance!
