Perhaps 1 star less that part 1 and 2, because I felt that on the perhaps most interesting chapter of this third part, the Lorenz system, we could have spend more time and there weren't any assessment questions on this last section of the course. For the rest the same high quality of the first 2 parts of which I copy my review down here. This part 3 was perhaps a little (but not too much) more challenging than part 1 and 2.
Excellent introduction to the subject in three parts. Next to techniques, the course also spends a lot of time on conceptual understanding and how/where differential arise in practice/physical applications.
The prof has relaxed and easy to follow lecturing style and the course staff in highly involved and helpful in the forum.
A little calculus (differentiation and some integration) background required, but the course is rather easy going.
