This video discusses the topics I recommend you focus on to boost your chances of achieving a higher grade (A/A*) in AQA A-level Biology Paper 3 2024. I examine the frequency of different AQA topics from past papers based on their raw marks and cover what the UMS grade boundaries were for each paper 3, from 2017 to 2023.
