In a group with international students who have terrible English

Basically title. I’m in a group with two international students and their English isn’t good. For example, if they send a text in the group chat it reads as though it was put through a translator 20 times. You can tell what they’re trying to say but it just doesn’t make sense. Whatever I say to them they don’t know what I’m saying. So, the whole premise of the assignment is lost on them, I’ve tried to explain it to them so many times but they can’t grasp it.

I have no clue how they’re going to contribute to the writing portion of the assignment. I fear I’m going to be editing and rewording both of their works if I want a good grade. If I don’t do that then the writing portions won’t make any sense and we’ll get a bad grade.

This feels ridiculous, I get that language barriers are tough but I shouldn’t have to take on three times the amount of work than I’m expected, it’s not fair. I simply don’t have time nor is it my responsibility. I would’ve thought expectations would be higher considering this is a masters programme.
