I had a similar situation with a Grad School course.
At the first meeting, the Professor announced that we were to take the same seat for the duration of the course so he could more easily remember our names. No problem there.
However, right behind me was a group of three ladies. It turned out that the two on the ends were not proficient in English and the one in the middle was their interpreter. She kept up a sentence by sentence simultaneous translation during the entire two hours of the class. I have to admit that it was a spectacular performance but it was almost impossible to concentrate on the lecture. I knew I couldn't sit through two hours, twice a week for 13 weeks with this going on. I wasn't the only one.
Even the Prof was giving them the stink eye.
He must have had a 'Come to the deity' meeting with the trio because they never came back.
I was pre-law for my Bachlors. Decided teaching was a better fit but I was at a private university. Dad told me to finish the poli-sci degree then I could add on teaching at a public university.
Because of some of the quirks of my Liberal Arts University - I had to take a few freshman and sophomore classes to qualify as a teacher in Texas. (US History and Texas History for example - I took Russian and Japanese History for non-western cultural credits those didn't help with teacher certification.)
One of the classes I had to take was Human Geography - code for human evolution. Small room only 3 or 4 rows deep but the rows were long. I was smack dab in front of the professor not 3 feet away and I coudn't hear him because these two women behind me kept up a constant dialogue about how requiring this class for teaching certification was a violation of their first admin rights. It was a Tuesday - Thursday 1 1/2 hours class with a break. I asked them to be quiet. The Fundamentalist Preacher sitting next to me - asked them to be quiet said they weren't be required to believe just understand a widely accepted academic school of thought. They kept it up. So Preacher and person on my left, and I started asking the professor to repeat things, being very specific why we couldn't hear him. He gave them 2 options shut up or leave.
One of the women left the class. The other continued.
For the next 2 semesters this woman I butted heads. I got so tired of the some of the professors paying lipservice to equality but letting this woman make racist comments that I started telling them and her that what she said was unacceptable. Then many of our classmates started speaking out against her racism.
We ended up taking our certification tests in the same room. I finished both tests in about 30 min (you had 3 hours) and left quietly. She told our adviser that I had walked out without finishing the tests. I explained I'm just a fast test taker. When the scores came out the woman asked me "How bad did you fail?". Turned 10 different shades of red when I told that I had missed only 2 questions on one test and 1 question on the other. She had failed and tried to file an appeal because I had "disrupted the room by leaving". Now the room was former open concept cut up into classrooms and stuffed to the door with desks. I would have gone stark raving mad if I had to attend HS there, but I left as quietly as possible.
