The pupil.

When teaching someone to drive, you find there are 2 types of pupil. The first wants to be completely ready for their driving test and so as with the theory test will spend hours and hours practising until they are as ready as they can be.

The second type, as with the theory test, knows that to give the needed stimulus to prepare for the test, they first need to be given a definite date to work to and only then does the pupil find themselves sufficiently motivated enough to fully prepare for the the exam.

And that's where there is a problem!
