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.
There were actually three professors teaching this class: Cohen, Sautet, and Rahardianto.
Cohen: I’ve heard bad things about him, but he isn’t as bad as they say. His lectures are on the boring side, but they are actually fairly useful. He does have useful things to say that aren’t written on the slides. His test was written well enough, but basic mass balances aren’t too hard to write.
Sautet: His lectures were boring, but they definitely helped digest tricky concepts on introductory thermo. That said, his lectures could be more clear. His test could’ve been written better.
Andi: His lectures were slightly better than the other three. Still boring still, but again, helped us digest concepts and word problems. His assignments and tests were confusing and unclear, but he did end up teaching the hardest section of the class at the end.
Overall, this class was fair. It definitely wasn’t a cakewalk, but the homeworks were very manageable, besides the MATLAB assignment. The MATLAB assignment was far harder than it had to be, but Andi literally gave us the code and answers for two questions. Also, HWs are graded on correctness, so if your numbers are slightly off, you'll lose points. Quizzes usually had a question or two that almost everyone gets wrong; don't sweat it if you get all 3's and 4's out of 5, since this class is curved and quizzes aren't worth too much. I actually did pretty poorly on HWs and quizzes compared to others yet still got an A+.
Tests were similar to the homework, but more extra practice like old exams would’ve been helpful. The lectures rip straight from the textbook, but reading the book beforehand will help. The book can be a pdf or whatever, no need to actually BUY the book.
Class was curved in favor of students. I also got something like 4.5% extra credit too.
Not much to be said really, the class is required and gives a good overview of the field as a whole. As it is for the majority laying down the foundation for future coursework, it can be a little boring/menial but not sure if it would be any better with a different instructor – I recommend going to TA office hours and reading the text. Weekly problem sets, quizzes in discussion and 2 midterms and a final, some (i think around 2.5%) extra credit given.
This class seemed to make easy concepts much more complex then they needed to be. At first the mass balances and DOF seem very hard and by the end it you will be able to solve them barely even thinking. The issue is to much junk is included in the power point for lectures, you need to find the bare basic and just learn those few points very well.
The class is taught by three professor (Andi, Cohen, and Sautet) but it doesn't really matter they are all the same, boring power points, fail to test key concepts in meaningful way, and then just make the test like HW problems (So just do the HW really well)
Mid 1 20% In week 4
Mid 2 20% In week 7
HW 15% 8 problem sets in total
Quizzes 10% Once a week at start of Discussion
- Note if you get over an 90% on the final you receive an automatic A in the class, class curved to an 83% (fill out teacher Eval. to get the extra credit)
The HW is hard, will take 4-5 hours per week, is graded on correctness and chegg has only wrong answer so don't check online but rather with a friend. If you can solve all the HW problems by yourself then you will do great on all the test.
The quizzes are the hardest part because only 5 questions a week and all conceptual so make sure you memorize key equations and facts from the previous two lectures before the quiz a few missed questions drops grade by a lot.
Midterms and final very similar. Midterms get 2 hours for each, final 3 hours. Each test has a few multiple choice problems at the start like the quiz questions and 3 writing problems on the midterms and 4 on the final. The writing problems are very long and multi part like the HW requiring lots of math. So make sure you are able to not only solve all the HW problems but solve them quickly as many people run out of time on the test before finishing. Know how to use math solver, solve system of equations, and store variables on your calculator will greatly increase your speed on test (Can use graphing calculator at all time). Also know how to read the important graphs.
You most answer all questions on all test if you leave any bank your score will decrease dramatically and will make it very hard to get an A.
