I'm Etalie, I'm currently studying for my AS levels and will (hopefully) be posting revision entries on psychology and sociology.
I previously uploaded posts on GCSE revision. If it helps you then great! But I'm not an expert on anything AT ALL so don't rely on everything I post.
(Also, I'm not taking credit for any of the pictures or info here, it's all off google images, notes from BBC bitesize and CGP revision guides, textbooks etc)

(NB - GCSE: italics in the science subjects are things that are only in paper 2!)
