Not sure I totally understand Grahame but no, there will not be any charge for a re-evaluation for any of us. Had we failed the course and had to take it again then there would of course have been a charge for this.
GUE believes in diver development and will look to find the best way to achieve this in individual cases. If further 'instruction' is seen to be required then this may mean that taking a course again is the best option and the result should be a 'fail' - so simply taking part and swimming a bit is not enough
However, it may be that an individual has to go away and practice a few skills in a certain range, or simply do another dive with an instructor to demonstate competance and consistency. It is nice that instructors are able to tailor results to suit this aim.
