Tough professor, lecture presentations suck. He derives the equations really fast and he doesnt elaborate on them. There is no depgh to the material presented which although it doesn't screw on the hw it screws you on his test. I memorized the equations, did all of the hws, even did and understood his old practice examsbut I still wasn't prepared for his final.

Spring 2020 - Professor Zheng knows the material very well and provided solid examples of how to do specific problems in each topic. I feel like he had a good course schedule of chapters and worked his way through each section efficiently. He was adept with Zoom from day one, asked for frequent student input, and developed an equitable, straight-scale grading format that was fair and well-suited for remote learning. The professor really cared about us learning the course material, and he shared a lot of his interesting research that related to the content learned in class, which was fun. I cannot recommend Professor Zheng enough, and I would happily take another course with him.

Summer 2025 - Professor Zirakian was great. He did an absolutely amazing job at ensuring we learned the content. He had written notes, recorded lectures, and the textbook for us to learn and you could use whichever you liked. The content was divided well, the homework was enough to learn but not overwhelming, and he was super helpful during office hours. The tests were VERY easy, like easier than the homework easy, but they still covered all the content, so they both ensured you learned while not being difficult. The only criticism is he was incredibly blunt especially over email, and his email replies weren't always super helpful, but otherwise this man was a treasure. Highly recommend.
