What is a good student?

I’d appreciate if you could proofread A and B.

A) To me, being a good student is more than just being able to focus on studying. It also requires students to be able to get along and work cooperatively with other students. I believe that social skills are one of the most important skills they need to develop before they get out into the real world.

B) I agree that the most important quality of a good student is being able to focus on their studies. Students who can do that are more likely to have the ability to maintain concentration and focus on their tasks, no matter how difficult they are. These are important qualities to have if they want to achieve future success.
