Best approach is use other people’s notes and your own knowledge to formulate ur own notes. Having a set of notes there when you are writing your own is really good because if the person has scored well who made the notes then u will see what kinds of things they write about, but being able to write it in your own way so you can understand it in ur notes document will help you most
Dot point books are also really good too they give you questions based on syllabuses which are helpful for exam preparation. The questions could also be used as notes
^ +1 Dot point is awesome too. I would use a combination of everything but just be careful using other people's notes since there's always a chance they could be wrong!
Does anyone have an alternative to Dot Point, btw?
