"What sort of things might I fail on?"

Among the many reasons for failure, the most common are:

  too long a briefing or one which is muddled or repetitive;

 expecting too high a standard from the 'pupil' in the beginner or parttrained stage;

  not instructing at a level appropriate to your pupils needs (over or under instructing)

 inability to recommence instruction at a different point or to go back and explain again;

  failure to detect faults;

  treating a 'pupil' as a novice in the trained stage;

  inability to adjust the content level of the lesson to match the 'pupils' knowledge;

 demoralizing the 'pupil', eg, "The Examiner will fail you if you do that on a test".
