Lab is infinitely harder at UVA than lecture is. The concepts are actually very easy. The lab reports are a breeze to write, even though they are detailed. But when you get to a final that has half of its questions in the form of "Which of these are/are not involved in the synthesis of X", and the answers are always A,B,C, A and B, A, B and C, then you run into problems. Especially when the average of the class is set to a C, and pretty much whatever you get on the final is what you get in the class. I got an A- in both lectures, and a B and B- in the labs. Go figure.
