Engaging with case studies and real-world scenarios enhances practical application of theoretical knowledge. Practicing mind mapping can help visualize relationships between concepts. Furthermore, participating in debates can sharpen argument formation and rebuttal skills. Finally, maintaining a journal for reflections on learning experiences promotes ongoing self-assessment and evolution in thought processes, essential for effective examination preparation.
