Rubbish week

Not a good week as far as tests are concerned, no doubt my pass rate would go up if I didn't support pupils who need extra help to get through the system.
Pupil 1.
Lovely girl who I have only taught for about 4 months cos she had taken a test previously and failed.  She said herself that she didn't feel prepared for the test but we worked on it and we both felt she was in good control and was very aware and totally ready to take to the streets.
Every lesson she comes bouncing out of the house before I even have time to finish parking.  She is bubbly and lovely throughout the lesson but still works really hard and so is a very reliable and competent driver.
But she can't pass a test!
She introduces a new fault that she never does, e.g pulling on to a roundabout with a car coming cos she is scared of failing for hesitation, pulling out when she is flashed without checking for the overtaking car, and the best was a 3 point turn without moving the steering wheel so she just kept going backwards and forwards (?).
I promise you that without the examiner she drives really well and is totally safe or I wouldn't let her take a test at all.
Pupil 2
I have taught this girl form the beginning and her sister before her.  As a 3rd year law student she is surprisingly slow at learning but she cannot be faulted for effort.
At the beginning she was very challenging because she just did not have the ability to retain information at all and so we spent a lot of time reviewing the previous lesson and often having to start from scratch.
But she was the first pupil I introduced to Client Centred  Learning (Coaching) nine months ago and she flew with it. If I ask her a question I don't get an answer until she has really thought about it and so the reply is well considered and insightfull.  She has become excellent at self analysis and improvement and has hence become a really good driver even though it had taken 2 years and 84 lessons.
Again she can't do tests.
On her first test she came away with the usual few minor faults and a serious that could be put down to nerves.
Her last test on Wednesday was a disaster.  20 minor faults, 5 Seroius and a Dangerous so the test was abandoned and the Examiner walked home!
He spoke to me, with her permission and said that it was as though her vision had closed down and so she couldn't see ahead, a common side effect of panic, and so her driving was all over the road with him having to intervene regularly to avoid problems.

The problem I have is how do I help these two decent, safe drivers who have got now psychlogical hurdles to overcome.  So against all my better instincts I have had to suggest to them that they see their GP to see if they can get any medical help to handle their panic.
On the other habnd I am really fond of both of them and will miss them terribly when they eventually sort it out.

So that is why I have a rubbish pass rate but also why I love my job helping the girls that every one else would have given up on.
Come on kids....you WILL do it x
