What is good about being able to assess, or grade, your own work? Well if you are able to grade your own work and you see that you did some thing wrong then you know how to fix it. for example if you were able to assess your math homework and you saw that you did a problem wrong, you would be able to fix it and get a better score. It can also help you a lot in school, you would be able to get 100% on most of your work which means good grades, which means good collage. I want to eventually become a vet, I would need to figure out whats wrong with the animal, I would need to assess the animal in order to help it.
