There's nothing too difficult about A2. It's just more content than AS, so if you were struggling with workload, you'll struggle even more and find yourself spending hours learning material. However, you do go over some topics you've already done like approaches/research methods just in more detail, so it's not necessarily new content that you are learning. This being said, A2 psychology places much more of an emphasis on analysis and evaluation rather than simply recalling the material so this is a skill you need to master. A2 psychology is also synoptic, meaning you'll have to draw on your knowledge from different areas of psychology to illustrate your ideas. The A2 mark scheme is much harder than AS, you have to write much more material to be worthy of a mark and to score the highest marks in the top bands, you need extremely detailed and thoughtful analytical points, for example:
At AS, it would be sufficient to write this for full marks when writing about determinism:
The biological approach is deterministic, meaning it claims all behaviour is caused by behaviours outside of our control. This a weakness of the approach because it means we have no free will.
At A2, for full marks:
The biological approach is deterministic, meaning it claims all behaviour is caused by behaviours outside of our control. This a weakness of the approach because it means we have no free will. This has implications on society, especially on our legal system since it provides offenders an excuse for their behaviour and nobody is responsible for their actions, which is clearly not the view we have of ourselves. This being said, determinism is a strength because it is consistent with the scientific approach, it allows us to identify which factors are causing our behaviour and therefore lead to practical treatments which benefit society, such as behaviour modification for offenders.
Can you see the difference in detail?
Just make sure you revise constantly through the course. This is more important at A2 than AS because of the sheer volume of stuff you need to know, last minute revision will get you nowhere.
Good luck!
