If you have done the hsc can you please give me your bio notes i will pay 30 dollars for themFrom personal experience I did accelerated biology and received a band 6. Biology in Focus is a good book in terms of content. However Pearson allows for a better understanding due to the variety of worked examples that are offered to readers. Additionally, Success One Biology has an enormous collection of past paper questions which allow you to excel in the subject. Good luck with studies!
