Enlist the help of a Road safety authority (R.S.A) Approved Driving Instructor(ADI). Ask for their ADI number, a five digit no (34000 upwards). They should know it by heart. If they don't have an ADI no. they are not a qualified instructor. It is illegal for anyone without an ADI qualification to give driving lessons for payment. You can see the list of ADI qualified instructors on the ADI website.

Listen to the testers instructions. If you are unclear ask the tester to repeat the instruction.
Know your car. What are all the buttons for? Do you know all the fluids under the bonnet.
