Imagine that your character is part of a high-school clique..

• Would they be popular? Sporty? Nerdy?

Pony-Boy would be a nerdy Greaser because he is part of the Greasers group. But he is actually really smart.

• Would they turn in all of their work on time?

He would turn it in all of the time but his friends and "family" wouldn't. 

• If your character IS a high school aged student, describe how they interact at school with others. What does this tell us about them as a person?

He does really good in school and he always turn in all of his work on time. I think that this shows that he is a great smart and talented guy.
