Final Year student now.
I'm still uncertain about taking psychology into postgraduate studies purely because I'm not keen on the idea of jumping straight into education straight after this one. Maybe in 1-3 Years, but not next year. Currently I'm not so keen on the idea of educational psychology anymore (Due to it's focus), but I still want to put to use my knowledge of psychology into education still, which has pretty much always been my goal.
Asides from that. I don't regret it at all.
Neuroscience is pretty much the least interesting aspect to me, not because it's difficult in the sense that it's harsh to grasp, but more in the sense that there's a freaking load of small details to recall which I honestly don't have patience for. You could say the same applies to social psychology but it can focus more on the largest aspect.
My favourite module so far has been learning about the basic ideas behind cooperation, conflict and altruism... (Basically utilises some game theory). That was pretty fun.
