Generally the BSc courses cover stats and research methods, cognitive, developmental, biological, issues and debates, social and individual psychology, as well as your research project. And then there are options to take electives, which vary between uni’s. For example evolutionary psych, spirituality & religion, sleep, vision, psych and the media etc.
Different courses offer different optional modules in addition to your core material. Core modules in most courses are: developmental, cognitive neurological/bio psychology, social psychology, research methods, statistics, and dissertation (I might be forgetting one or two) with optional modules scattered around in each year.
