The Great Gatsby, what he's got about improving his mind

Could you please tell me the meaning of "what he's got" in the following passage from the last chapter of The Great Gatsby?

"Jimmy was bound to get ahead. He always had some resolves like this or something. Do you notice what he's got about improving his mind? He was always great for that. He told me I et like a hog once and I beat him for it."

Thank you.
