17 1/2 is way too old to be joining the AAFC as a cadet. Most of your NCOs are going to be 2-3 years younger than you. Your course mates are going to be in Year 8 and Year 9. If you haven't joned the AAFC by beginning of year 10 you've probably left the run too late to progress through and get maximum benefit.
