The professor is extremely nice and helpful. His lecture notes are very clear, so I was always able to follow along. The pace of the course is reasonable, and I am able to strengthen my understanding of the concepts through working on HW problems, which prompt you to think and practice but are not too challenging to the point that you just have no idea how to solve them. The midterm and final tests are also very accommodating, where we had open book and notes and questions that focus more on implementing the numerical methods rather than on the very theoretical stuff (at least for the midterm). One thing I'm not extremely comfortable with is using Matlab because I've never really used it before, but it should still be ok to handle if you have some programming experience before. Overall, I would really recommend taking the course with Professor Chenfanfu Jiang!
