Tae is a pretty cool dude (he'll ask you to call him Tae and not professor, although no one seems to remember this). His lectures can be a little dry sometimes, but he goes over plenty of examples that should help you on your homework. I would recommend sitting near the front of the class since his handwriting can be a little small (although it is very neat), but also so you can hear his jokes better.

The TA, Roja, was very helpful too. In discussions she would go over problems from the textbook that were similar to the homework questions you had and in office hours she would guide you towards finding the answers to homework without straight up giving away the solution (which I think is more helpful anyway).

Tae's exams were all right (~60% average on both the midterm and final if I recall correctly), just remember to keep the general equation of a second order system in the back of your mind since that thing shows up everywhere. I think the low averages can be attributed primarily to the very easily found solution manual of the textbook and the numerous students who just copied the homework solutions and then got destroyed on the exams without ever understanding the material.

Also, a really, really cool thing that he did was if you bombed the midterm, he would count the final as 70% of your grade instead of 40% final and 30% midterm ("I believe in redemption"). For this, Tae Roh has earned my 'most badass professor' award.

The Matlab project (10% or 15% of your grade) about the inverted pendulum was pretty easy, as the Matlab stuff you had to do for homework pretty much teaches you what commands you need to use to do the project (root locus stuff and dominant pole design).

Overall, Tae is a pretty decent professor that I would take for other classes if given the option. My only suggestion is that I nope next time around he decides to discuss some of the industry applications of what we learn in the class (even if they're really basic) just so people can appreciate why we have to take EE 141 in the first place.
