I'd suggest that you think very carefully before starting an FI course.
With a glut of FIs already looking for work, there won't be many posts available for newcomers - and it'll be an employers' market.
I question the morality of FI schools touting for trade when there's already a surplus of FIs out there....
I think that I'll retire from instructing for a while (except as a GR Examiner); it's just too expensive to maintain my qualifications and Class 1 with so little work out there. And it's time us old farts stood down to let the youngsters have a go!
