Unfortunately the A1 Notes were very poor. As they are handwritten, they are hard to read, they are also not very informative or summative. There were mistakes that subsequently made the answers in the examples given wrong. Lots of work was also left out. Thankfully the A2 notes were much better as they were typed out and did not use unnecessary colourful drawings and headings for no reason, making them much more concise and easy to follow.
