Dr. Sagasti is definitely very knowledgeable and he doesn't just give you the answer when you ask a question. He can go pretty fast during lectures, but office hours were definitely super helpful. However, this class definitely covered a ton of material so the final was very long. He likes to ask "make your own experiment" type questions so you need to know all the experimental techniques and how to analyze results. I was lacking in that area -- though I knew the techniques and results I would want, it was hard to put into the concise words that he wanted. Overall, learned a ton in this class.

i can't stop laughing at the person below me who obviously seems...very passionate about his/her feelings about the TA. Anyway, I took LS4 with Sagasti and he was great. He sounds like there's something stuck in his throat but you'll get used to it. Take him if you can!!
