This class was tough.
Count on putting in some serious hours outside the classroom during this course if you want to be successful. While the material is not necessarily difficult on its own, it is approached in a very indirect way during the lectures, with a substantial amount of time devoted to supplementary topics and real world applications of the methods, as opposed to actually lecturing on the methods themselves. They also use some very "Delft specific" notation and jargon in the course so if you can find open courseware notes for a similar course at another university I highly recommend it. Additionally, I'd recommend having a look at the past exam papers on blackboard right at the start of the course so you have a better idea of what is important, because the lecturers, while very well informed, don't do the best job of expressing what the most critical elements of each lecture are.
The guest lecturers at the end of the course were really enjoyable and while they weren't necessary for the exam, they did a good job of adding some "color" to what is ultimately a very dry and tedious subject. Seeing how the material is actually used in a professional setting for policy decisions was a nice way to wrap up the course. I also highly recommend the Q&A sessions with the teaching assistants. I would go as far as to say attending them is critical for passing the exam.

Advice for students:
Attend the optional Q&A sessions. Start looking at past papers right from the start to identify what is actually important in the very dense lectures, and find notes from a similar course at another university to help clear up any confusion with lecturer specific jargon/terminology.
