Whilst I have sympathy the other posters are right, once the test is passed you might be thrown the keys of some random car to go from A to B, you might later drive a hire car, you will not get an induction for either .e.g my brother in law once could not start a hired Volvo abroad as he did not know he had to depress the clutch to get the engine to start, I once had to move an XK8 and could not work out how to operate the handbrake.
The fact is cars do vary, clutch bite varies, even handbrakes (Merc Auto handbrake operated by a pedal by foot, release a pull on the dashboard)
My son is currently learning, he is fine on manoeuvres in his instructor' car, he is painful in my wife's Fiat 500 (Burning clutch), he is yet to get the feel and is therefore not yet test ready-once he can go from one to the other without high revs in the Fiat at low speed to prevent stall he will be ready.
