This video introduces the PERO system for learning, developed over seven years. The speaker, Justin Sung, explains that effective learning is about systems, not just techniques. The PERO system (Priming, Encoding, Reference, Retrieval, Overlearning) aims to boost learning efficiency by optimizing the processes involved in acquiring and retaining information. Sung shares his past struggles with learning and how implementing this system significantly improved his academic performance. He also offers a free quiz to help viewers evaluate their own learning systems.
