In NC I think an attorney can dispose of a client's property or act as an agent for a buyer and charge a fee plus other such duties of the law practice clientele.
But in order to list properties for sale and work with buyers only as their real estate agent and get paid a fee, they need a real estate license, from what I get from the wording.
As far as exam prep goes and a book to do it from - just do a Google search or contact a cram course provider in Utah, or community college that teaches real estate courses.
That way you get to pick your own poison
