When it comes to our assessment, we refer to 70%. On crucial points, you have to have 100%. Not 70% for each exam question. Some points have to do with the way to carry out an audit, and for those you need 100%. There can be no failure.
However, there is some margin for issues like marking or completing documents. These points are less crucial, but they remain important. However, they do not relate to the device's accuracy. That is why it is 70%.
