After a couple weeks of my new chemistry class, Maya asked me about oxidation reduction reactions. Our teacher had already covered it pretty deeply, but I guess she forgot some of the details. After I explained what I knew, she mentioned that she didn't see me in any of the lab experiments... which is because I wasn't actually part of the class. I was just sneaking into the lectures. I explained how I didn't have the time to attend that part of the class. Maya was shocked because she said without the lab sessions it would be almost impossible to succeed in the class.
