As others have said, your list is probably not inappropriate in the average 7 year-old, but it would make me twitchy in a kid who can and wants to read grade 4 books, but then seems to find something frustrating and getting in the way that makes him stop.

Your list is very familiar and (in our case relates to both visual processing processing issues as well as dyslexia). A smart kid who seems like they can read but fights it, is always worth a careful look.
