How hard is psychology BSc Hons at uni?

I am interested in studying psychology at uni, however I wouldn't call myself the smartest person around. Does anyone have any knowledge as to how much coursework/studying is involved during this course? Would I spend the whole time doing coursework and have no time for socialising?

Thanks

If you schedule time appropriately for your assignments, it's fully possible to do well both in and out of the course.
