Daniel is one of the best TAs at UVA and he always went the extra mile. His discussion examples were so helpful and similar questions popped up in the test. Highly recommend going to discussion because it really does help and it's never boring. He was always willing to repeatedly explain questions, and even broke them down in different ways to make it more understandable. If you're still confused, go to his office hours (although I doubt you'll need it since Daniel does such a good job explaining during discussion).
