When I was in a biology class in high school, I was tutoring my friend and helping her understand the parts of the heart. We labelled the whole diagram and had been studying it for half an hour only for me to finally realize we had been studying it completely backwards that whole time.

I love the colours in this comic!! Also, this story if hilarious, I’ve definitely been in the same situation where I was studying all wrong and found out later on after hours of doing. I hope you two ended up doing well regardless of this!!
