I found the year 12 move from medicine to nursing to be an example of what I call the 'careers teacher effect'.

Yes I wonder about the knowledge base of 'career teachers'. I have worked across several industries and I would be loathe to start advising someone about a career path....What do these career advisers know? Certainly the one I had in High School was pretty much useless. Or maybe her misrecognition of me and my capabilities guided her poor advice.
