In spring 2023, I took the course EBU5476: Microprocessors for Embedded Computing, where Dr. Matthew Tang assigned us to create exam-level questions based on course topics. My task involved devising a question on ARM architecture, reviewing course slides, and refining the question with feedback from peers and Dr. Tang. In spring 2024, Dr. Tang and I further refined my question for future use. This co-creation process, involving collaborative refinement and feedback, significantly improved my skills in collaboration, critical thinking, and communication. My question successfully became part of the tutorial materials for future students.
