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.
