If I could say one thing about this class, it's that it's all memorization. I'm not exactly the strongest student in that regard, so I would say this class wasn't hard to understand but rather hard to memorize all the content for. Professor Banerjee is pretty nice, pretty clear in his lectures, and his slides are super detailed, which is good and bad because you should know basically everything on them. His tests weren't very tricky, as he didn't allow cheat sheets or anything, but they were definitely pretty ruthless with testing any aspect of the slides (facts, drawings, graphs, etc.). I personally felt as though the tests were graded relatively harshly, as there's little partial credit and a lot of emphasis on having the exact answer down. (For example, out of a 30 point problem, I had all the right steps but the wrong numbers in the beginning. He gave max 13/30 points, which I felt was a little unfair, but to each their own.) He curved the average to a B (around a 5% curve?), so I guess you could take my experience as that of the average of the class.

This was a class I took for fun (not even for elective) in my senior year, and I thoroughly enjoyed learning about materials science, which core ChemE's don't get a lot of. There was a lot of content, and there's some chemistry, e.g., in polymers and intermolecular bonding, but everything in exams is taken from the slides.

Speaking as a Mechanical Engineering major, this course was not especially difficult, although the course covers a lot of material. I feel that Professor Banerjee was a great lecturer, and I appreciated his energy in teaching this material. Given the nature of the volume of material, each lecture was a solid 2 hours of content, administered through detailed PowerPoint slides. Exams and assignments were quite reasonable, and pulled directly from lecture slides. I enjoyed this course a lot more than I expected, and am very glad that I took Banerjee.
