I took Dr. Han's courses starting from the theoretical lectures all the way to the problem-solving sessions. While the content could have easily felt overly academic, the doctor explained the overall flow and provided examples through a structured storyline, making the lectures easy to understand and highly informative. Beyond just exam preparation, I was able to learn theories and knowledge that are directly applicable to the project work I am currently performing. I highly recommend this to anyone considering the course, and I especially suggest following the doctor's lecture flow and making sure to listen "until the very end." Thank you.
