I moved to Psychology HL from Mathematics HL at the start of grade 12, and right now I have to catch up one year of Psychology HL, which the topics cover biological approach, cognitive approach, and sociocultural approach. I can self-study myself but I really don't get how we do the exams.. Do I really have to study everything? Or is there an efficient method of studying these topics? Like I heard something about the Learning Outcomes that can help with the exam questions, but I really don't understand it. Can someone please explain?
