Prof. Narins is one of the few good professors I had at UCLA. His lectures are well organized and he really teaches you everything you need for the midterm. No need to look at the book. Average for my midterm was 75% which is not bad. His test, like he said is fair. Just make sure you know the lectures really well and memorize everything in it. He also asks weird EC questions on his tests, like geography stuff because his son does something on the field. Overall, he's a great lecturer and friendly at office hours
Professor Narins is freaken awesome. This guy knows his stuff. He can present something that is highly complex in a way that is easy to understand. He keeps his students engaged by asking questions and telling the most interesting stories. Tests are fair and straightforward. I highly recommend Narins. He really gives you an appreciation of the sciences like no other.
