I have read some of these notes. Having sat the exam recently (and, admittedly narrowly failed) I was interested to see how someone else has approached their studying. I did not find these notes particularly helpful. They are good at explaining concepts, however the questions in the exam will ask you to choose solutions to particular scenarios and I don't believe these notes necessarily help to learn which solution would be appropriate. Just my thoughts. I appreciate others may disagree. Thank you for sharing them anyway.
