Human biology, physiology and pathology have been all I've known for the past 4 years of uni and so when my friend told me that she was doing a physiology unit for the first time ever, I totally jumped on the idea of helping her understand some of the concepts she was finding difficult. It was a total win-win situation because it would help her, and it would be awesome to refresh my memory too.
We covered oxidative phosphorylation, substrate-level phosphorylation, the Kreb cycle (aka the Citric acid cycle) and a whole bunch of other things all related to carbohydrate metabolism. Even though I had only briefly touched on these during my undergrad degree, I found that it was quite easy to understand having done so much physiology and being exposed to similar mechanisms and a lot of the terminology the books used.
I've never done anything close to tutoring a person in what I've previously studied because I've never thought that I have sufficient knowledge. If I didn't have this mission to try something new each day I may not have had the confidence to give her some tutoring, but we both really benefited from tonight. Seeing my friend's face light up after understanding a concept she didn't before gave me a whole new level of confidence.
