the questions offered in dot point are good for revising and the answers can be used as a starting point to later expand in your notes. However some answers are actually wrong which I noticed for biology... and some of my friends have also noticed for physics...
the answers are sort of okay, they are more like a band 4 answer. If you are looking to get a band 5 or band 6 answer, you will need to add more detail into your response. Detail in terms of key words and not in terms of writing lots of stuff that is repeated over and over again.
