Marta is a very nice person. She is very friendly and wants to help the students in this class. Her voice and lecture though did put me to sleep sometimes. The grade breakdown was as follows.
15% Quiz 1
25% Midterm
15% Quiz 2
35% Final
10% Homework
The exams were very conceptual but it was open note. I highly recommend printing every single slide because you could usually find niche problems or concepts that you didn't study but happened to be on one slide. Also find old tests because that will save you in this class, a lot of her test questions are reused. It is very manageable to get a good grade in this class and I would take this class again.

Pozuelo was a kind person and clearly knowledgeable about materials science, but she really was not good at lecturing. I didn't watch most of her lectures and chose to read slides and the textbook instead, but it was abundantly clear in the few hours I did spend that she simply does not know how to explain stuff in a way that is appropriate for an introductory class. The lecture alternated between basic level info that you probably already know to higher level info that was clearly not useful nor testable, with not nearly enough time spent at an intermediate level appropriate for the course. Far too frequently there would be questions on the homework that were absolutely not answerable with the content given in lecture, as if she somehow expected us to read 50 pages of the textbook every week as well as attend the lectures. The textbook, btw, is actually great and absolutely reading it is a great way to learn, but the quality understanding you can get from the book is way overkill for what the class actually requires and I stopped reading the book when I realized it was not time effective. Back to homework, the problems were a strange blend of dense computation and straight up short response to conceptual questions, in such a way that made it completely unclear what the professor wanted you to actually know. There were two quizzes, a midterm, and a final, of which the first two to occur were pretty darn hard, and the second two were way easier. There was a curve at the end of about 1/3 of a letter grade, which was annoyingly small.

TLDR; the course was poorly organized and unclear in its objective, and the lecturing by the professor was not worth watching. I would avoid Pozuelo.

lecture is super boring/exactly what's on the slides. you don't need to pull up to lecture, but the exams are kinda challenging. everything is open book/open note so you can usually figure it out.

Professor Pozuelo is caring and always wants us to succeed, so she wouldn't mind taking time to repeat again and again just to make sure we understand the topics. Exams were easy, 2 quizes and 1 midterm. Workload is fair and TAs are super helpful. Highly recommend taking her.

Professor Pozuelo was super nice and she was really eager to help, but sometimes her lectures or the way she explained concepts could be a bit confusing. The homework is very manageable, and her quizzes and tests were all open note and open book, so most of my studying was filling in notes with everything on the slides, since the test is mostly if not all things from the slides, so it's really helpful to go to class. Lecture's weren't recorded but she posts all the slides. Overall, it was a very manageable class, and I'd recommend taking it with Professor Pozuelo.
