Fall 2020 - This professor is new and this impacted how the class was structured, as I felt that the professor did not reach a reasonable pacing until later in the class (he would go fairly fast in the beginning where it was not possible to take detailed notes of everything). I did feel like I learned a fair amount about chemical engineering and the thought processes that we need to learn to succeed in our field. The homeworks were in "report" style, where you had to almost draw a diagram or description of every problem (usually around 4-5 problems each homework), restate each question in your own words, and state any assumptions you had to make for your solution. These homeworks took a large amount of time to complete and the pdfs I handed in usually amounted to 12-18 pages of written solutions. The first two exams for this class (the two midterms) were poorly structured to the point where it was nearly impossible to complete everything in the given time limit. The second exam was slightly better in this aspect, we had more time but the exam was still extremely hard (average was in the 40s). However, by the final exam the professor got a lot better at exam design since the final was extremely reasonable difficulty-wise and more reasonable to be completed within a time limit (yet we were given 24 hours). Overall, the professor improved over the course and I definitely believe you will learn a lot if you pay attention and be diligent in your studies.

Fall 2018 - Many reviews here from previous years describe this class as not too bad once you mastered the material and that's not wrong. But regardless of those reviews, remember that this class is THE ChemE weeder class and you'll be surprised at how bad of an end grade you can get. Monbouquette has complete control over how he wants to distribute the grades - for our year the percentage of actual A's given was somewhere around 10% of the class which is significantly lower than other years because it was probably judged based on the fact that the final exam was ridiculously hard and had an average of near 50%, which he was probably disappointed by. Beyond that expect a not-so-engaging lecture with endless examples of how to do endless balances in time-consuming problems that take endless time to complete, especially the MATLAB assignment which he gives you despite most ChemE's having zero MATLAB experience - this assignment will take a very long time, and you'll have only a week to do it if it was like our year. TL; DR: Weeder class, not that easy, grading depends on Monbouquette's opinion of class, material isn't terrible but super time consuming.

Fall 2019 - Just a heads up, CH-ENGR-100 is NOT a class taught solely by a single professor. For our quarter, we had around five different professors lecture across the span of ten weeks, each on their own specialty. As such, I will only comment only on the structure of the class and Professor Rahardianto himself. The major of your grades will be based around two midterms and a single final exam. In between are weekly homework assignments and quizzes in your discussions. The homework assignments, while not difficult, are in fact time consuming. It would serve you well to invest some time in learning Excel and Matlab in order to simplify your homework and finish it a lot quicker (a lot of people complained about taking 10+ hours to finish the homework, but if you're tech savvy, you can shave that down to 4 hours like me). It's still a time commitment, so make sure to start your homework early. The quizzes are relatively easy; simply go over the lecture slides for the week before your discussion and look at vocabulary and key equations, and you'll do fine. The midterms and final are very straightforward and similar to your homework. However, you are required to think critically, as expected of an engineer; the majority of the questions can be easily reasoned through even without prior knowledge, and generous amounts of partial credit is given. As long as you do your homework, and ACTUALLY UNDERSTAND IT, you'll ace every exam. The lectures themselves vary quite a bit in terms of quality, depending on the lecturing professor. I will only discuss Professor Rahardianto for this review; Professor Rahardianto is a new professor, and thus isn't exactly the best lecturer. However, he is very willing to help his students and provide clarifications, and is empathetic and flexible with assignments. I found his lectures best when you have a laptop on your lap opened to the textbook, which would provide supplementary information while he is lecturing. Don't worry too much about taking notes; he always posts the slides on CCLE afterwards. Overall, I found this class to be mildly challenging and definitely rewarding. This is basically a required class for all chemical engineers, and does give a good impression of what chemical engineering entails.
