Professor Naranjo is one of those physics professors who doesn't believe in plug-and-chug questions, there is not one number to be found in any of his tests. He definitely is one of those professors who grossly overestimates the class' background knowledge in math and physics, so lecture can be hard to follow. Although he cares about his students' learning and is actually pretty understandable during office hours, lectures are a lost cause - he is sadly not an engaging lecturer and his handwritten notes are impossible to decipher. He is quite lenient on homework - although it is not fully completion, if an earnest attempt at solving each question is made, with some reasoning behind it, you should usually get full points.

I'm sure Naranjo will have lots of negative reviews due to his difficulties teaching (especially at the beginning of the quarter), but I think he is a good physics professor and a great guy. It was his first quarter teaching, so the first weeks of lecture were pretty rough, with lots of stuttering. However, Naranjo improved dramatically by the end of the quarter, and he was very receptive of student feedback. He is clearly a warm and friendly person with a genuine passion for his students and for physics.

His teaching could be confusing, especially for material such as complex math and differential equations. Additionally, he taught VERY quickly, often going through multiple chapters in one lecture. Homework problems could be difficult at times, but if you go to his office hours he will work through the problems for you. Exams took a shockingly long time.

Overall, Naranjo was not the best or most polished professor, but he is definitely helpful and a very likeable person. His passion for physics really comes through.
