Not so fast with those rocks there, dd.
Australia only sent two courses of twelve to Bath. Of those, I understand 11/12 and 10/12 checked out upon return. Seems to be somewhat higher than the locally trained pass rate? Speaking for Sydney, we got six of the twenty-four and all of them checked out and have proved themselves to be competent or better. Perhaps you are suggesting that this happy result was just a function of our exceptional OJTI?
