I thought that the training was great. Especially as a foreigner, I didn't even know what 121 meant and had zero instruction time.
The study was real. We did a lot of group study and was also lucky to have made some good friends in class. We all helped each other which was really nice. I don't think anyone flunked, this was at the end of 2017.
I remember becoming vegetarian, because it was quicker to cook than meat. As I didn't have a lot of time to waste not studying, and it pretty much became a way of life.
