Winter 2021 - Jin is honestly really on top of it--she has her lectures well-planned and is very good at giving us a clear view on what we're learning. She warned us many times that the strength of materials portion would be way more challenging than the statics portion, which was a good heads up to not slack off. Lectures are long so it's kinda hard to pay attention the whole time especially on Zoom but every single word she says is very beneficial to doing well in the class. She also was very reasonable about due dates and accommodations and gave us more than one chance during the quarter to give her feedback on the class structure. If you pay attention in class, do all the psets, and truly understand the derivations, you should do okay. There was a midterm around week 6 and then a quiz and final--they were very fair in my opinion, but were challenging because you really had to manage your time well. I honestly just struggled a lot with accuracy in problem-solving since a lot of the problems involve a ton of algebra.
Fall 2020 - This class is really difficult because of the material, but the professor herself is pretty good at teaching, although she tends to go fast and sometimes she skips over small details that can make things confusing real quick if you're not paying attention. The lectures are all recorded so I recommend watching them at your own pace and going back/rewatching parts if you're confused. The professor is really helpful if you have individual questions and she responds to email, so as long as you ask her your questions you should be okay.
