I was the top of my class during college and I wouldn’t be without my study group. I got all the concepts easier than them, but having to force myself to explain it to them and take care that they understood it really cement the concepts. I’m doing an online MBA now, and I struggled during the first months because I had no study group, fortunately an extrovert adopted me into her chat group and with them I was able to come back to my Feynman method of study.
