Grade: B
May 17, 2024

I think he is retired but if he comes back, he was just okay. His class was the kind of glass where I had to chug a Celcius just to stay awake. He does care about his students. Exams are fairly hard but you can kind of predict what he is going to ask. I would not recommend him
