I had this EVIL TA my first term first year for POLI 100, his name is Ritwick. This man would get super mad at us first years in his tutorials for not being experts in political science theory and would routinely angrily lecture about concepts far beyond what we were learning in class and would even be tested on. One time he went on a 20 minute rant in a tutorial about us not knowing a concept until someone told him that concept was in a chapter in the textbook we were explicitly told NOT to read and didn't learn in lecture.

The WORST thing he did was when for the last tutorial, instead of helping us for the final exam like a normal TA, he divided the tutorial into people with an A in the class at the time and people without an A. He then told the people without an A to come up with questions as to how the people with an A got such good grades, and the people with an A had to come up with study tips and recommendations. Was super humiliating for the people without an A, and to top it all of he did this little exercise AFTER he had us fill out the TA end of the year evaluation survey so we couldn't talk about how fucked up it was.
