From a fellow BOS member:
"its roughly 30% chance you will pass the exam. You get two examiners, one who comments positively on your performance, another who criticizes negatively, and they debate against each other and whoever wins determines whether you pass or fail. They dont give you A, B or C etc but give you either award with distinction, award, and no award. Award means you satisfies the requirements to pass the exam. Award with distinction means you pass the exam and surpass all requirements. and no award means you fail.
It is possible to pass the exam in one year of practise, but the chances are less than half, so its advised you practise on average 2 hrs a day minimum."
