Summer 2024 - This class was set up very well for an asynchronous summer class - all of the recordings were fairly high quality, and the homework and exam logistics were pretty seamless. All of the exams were open note since it was online, and the exam difficulty reflected that, but access to all of the textbook, lecture slides, and other resources made exams pretty manageable. It's definitely easy to get behind in some ways, but the problem sets and exams were spread out far enough that you had to be watching the lectures to be successful. Professor Goorsky and his teaching team are well versed in the content (for the most part, some of the TAs gave contradictory answers went I went to office hours), and Goorsky in particular is a clear lecturer that provides understandable explanations of complex scientific concepts. All of his slides and recordings are available online, mirror the textbook for the most part, and if you dig hard enough there are external resources that can supplement your learning if the teaching time isn't enough. The content here is not unreasonable and none of the math requires much more than introductory calculus and basic chemistry, although I'm sure there are entire classes dedicated to a week of this class that would go far more in depth with the calculations and theory. For this class, it's mostly just plug and chug when it comes to math, although there's a fair amount of explaining and theory that many lower division engineering/STEM courses don't require. I honestly do feel like I learned a lot when it comes to materials, more so with metals since there was much more of a focus in the first half compared to the end with the other material types. This is a class where you can walk away with it and have a basic understanding of an intriguing branch of science/engineering.

Spring 2021 - When I first signed up for this class, I was actually quite scared due to the previous reviews. However, after taking this class, I can confidently say that Dr. Huang definitely deserves a much higher rating than a 2.6, and I definitely found this class quite easy and straightforward. --- This class definitely revolves around the textbook. Slides are based off of the textbook, homework problems are textbook problems, and sometimes, exam problems are ripped straight from the textbook, verbatim. So definitely know the textbook material; grind problems out, check your answers with Slader, and you're good. Homework is definitely on the level of exams. If you can ace the homework, you can definitely ace the exams. That said, there are definitely conceptual questions you need to know; you can't math your way out of this class. --- Dr. Huang's lecture slides are really good, and same for the slides that the TAs give out. I personally found them to be very comprehensive, and useful for exams. If it's not on the slides, it's not going to be tested. Even better, Dr. Huang releases slides before lectures, so you won't have to write stuff down at 90 miles per hour. Dr. Huang's lectures may be dry, but they definitely cover what'll be on the test. She also throws in some cool videos that explain concepts well. That said, she refuses to record lectures. --- The course material is quite interesting, and the exams and homework are definitely fair. Exam averages were 75 in my year, and Dr. Huang said that she'd set the average grade to a B+. Let's see if that ends up being the case.
