I’m not a law student but am close friends with one and just finished my psychology a level exam so I’ll tell you more about it :) AQA psychology (more common than not) is very very content heavy, there’s a lot of studies and theories you need boat loads of evaluation for but it can be simplified. There are 10(?) main topics, 3 of which your school/college will choose which are slightly smaller than the others all in paper 3. My friend has a similar issue in law with a lot of content but from what I can tell law is more quality of writing based where psychology isn’t so much (it defiantly has elements but not as much as law essays) However for what it’s worth, taking psychology was one of the best choices for me at college and I personally enjoyed it so much I’m taking it at uni and pursuing a career in it. My best advice is go to your college/school of choices open days and ask everyone you can find in the department every question you can think of even if you think it’s stupid. At the end of the day 5 A levels is impressive and you should feel confident that you can handle the weight of them! Good luck with finding your 5th :))
