| "...especially since most students do not compete with each other for grades."
I want to emphasize this so much. People are SO willing to help you with anything here, simply because we're not competing - we really are working together. For example, a girl who's really good in calculus will help me prepare for my 18.02 test, and I'll go help her prepare for her 7.013 test a couple days later. And there's no, "I shouldn't help, she'll get a higher rank" here because there IS no rank to compete for. It's all about just doing our best for our own satisfaction. |
