Utilizing active learning strategies, such as teaching the material to others or discussing with peers, can reinforce understanding. Creating flashcards for key terms and concepts allows for quick reviews and better retention. Summarization techniques, like mind mapping, help organize information visually, connecting ideas more coherently.
