How is the step for both of these subjects from AS to A2, did you enjoy them and would you recommend them ? I have no Idea which one to drop !
I enjoyed RS at A2, granted some topics are a little difficult but once you've got your head around it it's quite simple.
Philosophy you'll study life after death, religious language (sounds boring but it's actually my favourite topic), religious experience, nature of God (this is attributes from AS, not much to say on this topic).
In ethics you'll study virtue ethics, meta ethics (similar to religious language), sexual ethics, environmental ethics, business ethics, and then there is free will and determinism, and conscience. Free will and determinism and the conscience topic are my personal favourites in ethics, and if you like psychology then you'll enjoy those two topics.
Our teacher told us that people do tend to get lower marks at A2 but purely because of the style of the essay and how you're supposed to structure it.
But it all depends on what you enjoy.
