During my college days I was a member of various academic clubs, literary club and cultural club. It always helped me to learn what I don't know from others and educate others with my knowledge. I am happy to say that in this due process always my learning curve is an upward curve. In fact tutoring others helps you think even about things which we never thought of(based on the doubts of students).
It was a fundamental course on electric circuits and electronics. It was an online course. It was a great experience for me to learn and execute the same via a virtual lab.
