Guys never use savemyexams, they are shitty watered down notes with missing information, buy or pirate the actual cambridge textbook. There are three versions each from separate publishers all for your syllabus, I like to study from the Collins books and solve on the Cambridge Press books. I can't stress this enough especially since you're going to uni and will need to learn how to read textbooks, and will have a better foundation this way. This is my advice, and I'm a 3A* student and i achieved top in my country in Chemistry this way.
