Personally for me, I found it difficult to link the concepts covered in assignments/lectures to what was tested in the exam. You DO get a cheat sheet to take in (at least when I did it) which is a major help. The lecturers are amazing, really go into depth and want to help you. 5/5 for lecturers and 5/5 for assignments, just gave a 3 for the overall score because it can be difficult to grasp some of the concepts. Manageable workload.
