Statistics & stage 3
Just a quick reply to whoever was asking about the numbers that pass.
3% or so of those who start stage1 make it through to the college. However, be prepared to then lose some of your coursemates during that time to.
As a rough idea, out of our course of 29, only 5 made it all the way through the college without needing to re-take one (or more) courses. Of the remaining 24, half were chopped along the way.
If you get to the college, then you can feel happy to be one of the chosen few, but make sure you then work like hell to keep it that way.
Regarding stage3, the interview is as you would expect any interview to be - strengths, weaknesses, examples of life skills, how you worked with others etc etc. Read up on everything you have been sent, and be prepared to put over just why this is the job you want, and how your skills reflect why you would be good at it.
Good Luck!
