Here is a sample of feedback from the last run of the course:

"Very good teaching, although online there were lots of opportunities to ask questions and interact with the lecturers who were very responsive to questions".
Course feedback, July 2023

"I think the virtual experience worked well, the padlet and Q&A sessions provided a lot of opportunity to ask questions and it is appreciated that the questions were answered as they came up. It was nice to have the option to dip in and out to either work on the practicals on our own or follow along".
Course feedback, July 2023

"I had prior knowledge of the concepts covered in this course, but what truly stood out was how the course helped me connect the dots and see the bigger picture. This is one of the most valuable benefits one can gain from an educational program".
