we had to collaborate alot in one of my bio classes, 1 where i had a lab partner that did all the work without consulting me, so i dint know what was going on, she dint let me do any of the measurements,or whatever. then she disappeared midway into the semester(she dint even register for the class properly and only found out halfway) so i was left alone.

then comes the 2nd partner, who was absent most of the semester herself for health reasons. she touted as being in labs for 4 years(which she used in a rant against me), she was one of the most unhelpful people out there, she did not like the slides i was doing , and i should be doing it a certain way to make "digestible" to audience, but she would not offer any help, other than saying this or that is wrong. she was saying how she went to "talks" and conferences, she knows what she is doing, but she wouldn't offer how she was doing her part of the slide projects. as soon as she found out grades were separate for each person. she largely stopped helping(which was just criticizing) and only would get together to combine said slides.

later down teh line, i was thinking this btch was cutthroat asf, is biotech industry have people like this worried about thier perceived reputation so much, they would sabotage the group for thier own ends, also the PI/instructor was no help, but he has own problems, having an attitude. all the other groups in class dint have this much abrasiveness, and dint have interruptions like i did. losing 1 partner due to her being absentminded, and then gaining a btchy one.
