Do we have to know all of the studies for psychology a level? I did OCR b psychology in GCSE and I'm used to the idea of having to learn every single study inside out for GCSE but I'm not sure if that's required in A levels. It's such a **** take because there are so many. Especially in memory. I'm not sure whether I have to learn all of them or just a few that support certain theories, like Loftus' studies on eyewitness testimonies. But even then that's a whole lot.
