Koffi seems smart and an easy grader. Discrete math is basically algebra so the class was pretty easy. Homework assignments were not collected. Koffi organized extra evening office ours to answer homework questions on set theory, function theory, recurrence relations, graph theory, etc... Koffi's class just gives you a taste. Even though he took over the course in the middle of the session he explained the course material deeply. He made himself available on zoom several times during test days which I pretty much appreciate as I had the opportunity to come and ask clarification questions. Good Professor and nice dude! Also, solid replacement of Prof. Ozel!

Math 61 for the Summer 2021 term was originally taught by Prof. Ozel. When Ozel left in the middle of Summer session A due to issues with his visa, Prof. Enakoutsa came in to substitute. Enakoutsa did a nice job teaching Math 61.

Enakoutsa, while not the clearest lecturer (I strongly preferred Ozel's lectures to Enakoutsa's), genuinely cares about his students' learning and provides a lot of office hours for students to ask questions. He encourages students to unmute themselves in lecture to ask clarifying questions. While his answers aren't always the clearest, Enakoutsa is committed to improving his teaching ability. He takes student feedback on his teaching seriously.

His tests were rather straightforward and 24 hour open note. During the end of the course, Enakoutsa sent an angry email to everyone about one of his students' evaluations on his teaching (allegedly it said Enakoutsa interrupted students in lecture ...). He could have responded in a calmer, less defensive manner.
