You'll need an ROCC (A/G Certificate of Competence) as well to start training as an AFISO; the FRTOL doesn't 'cover' you for this any more so you need to take the full exam; CAP 452 is the present 'bible'.
The exam is fairly easy as the written questions will be covered by your flying training apart from phraseology which is in CAP 413. You're allowed 1 hour for the written which must be taken before a simple practical exam to test your phraseology.
