I agree – I don’t think it’s worthwhile to memorize specific studies. Understanding the big concepts and general recommendations is more important. Individual studies are included in the lectures to review specific interventions from the body of literature. If you read the associated articles, I would spend most of your time on the introductions and conclusions while just skimming through the methodology sections. Additionally, taking a look at systematic reviews is likely a more effective use of your time than digging too deep into specific studies, as review articles can be applied to a larger population and are more likely to be captured by the NCS exam. Hope this is helpful!
