These days the school or club is required to assess whether the student is ready for a written exam before approving each attempt. While we still have sitting rules this is also in the interest of the student. No one should be allowed to "show up and just do the exams" under current rules. Also, if he doesn't buy the 2014 versions of the separate Air Law and Operational Procedures books, he may get a bit of a shock in those exams.
