Hi John,
Reasons why one student gets an ''A'' and another student gets an ''F'' on the same exam has everything to do with the student and nothing to do with the exam.
I won't tell you that I never got an individual question wrong, I will tell you that I have never failed an exam.
I have a Masters Degree in Business, I clearly remember the University years, the classes and the students, a few did fall by the wayside for one reason or another, the rest were successful, with success having absolutely nothing to do with the ''science'' behind the preparation of the exam.
My life partner, God rest her precious soul, had a Doctorate Degree, Suzie oozed intelligence, by just walking into a room.
Our success, my success, and I'm very successful, has absolutely nothing to do with either bell curves or J-curves, that's a lot of nonsense.
Back on topic, dive students do not fail dive training because of the exams. Herd mentality instructors, who fail to take the time to ensure full student comprehension are just as much to blame for dive student failure as anything else.
My dive instruction has always been one on one, personally, I wouldn't do it any other way.
My eventual plans are CCR, and regardless of the cost, regardless of whether I have to fly an instructor in, or me fly to him/her, it will be one on one. ''My Dime - My Time"
Rose.
