Oscar makes this class much harder than the other TA's. Not only is he an incredibly picky grader, but he also refuses to review the material during discussion. Instead he tries, unsuccessfully, to have an irrelevant discussion on material tangent to the course.

Oscar is the worst TA I have met in UVa. Compared to other TAs in this class, he is such a harsh grader! He is very picky of your test answers! Other TAs do the review of context in lecture every discussion, but Oscar did not do that. Also, he will not lead us go through the review sheet before exams like other TAs. I definitely suggest not to take Oscar's discussion if you want to take this class.
