They're the worst. of my 3 labs, 1 of them is american and he just flies through stuff so fast that we can't keep up, and then we have no way to contact him if we have questions. Another one speaks poor english, so I got a 16/50 on the lab because I didn't understand what he wanted. I based my writeup on the sample on blackboard, but apparently there was a sample elsewhere I was supposed to use. And then my manufacturing lab is at least easy, but the student teachers are Indian so you literally can't understand a word they say. They kind of use motions to sign things to us.
