She is not qualified yet until after 18 months of residency here in the UK. I have recently applied myself and I am learning to drive in the other side of the road!
She needs time to get used to the "other side" of the road. It took me a while to gain confidence crossing the street and I had to re-wire my brain to get used to seeing big buses and lorries seemingly driving towards me!
She can start learning the Highway Code and I suggest you get the practice tests (free apps for your phone) and DVD at WHSmith for the Perception Hazard test. The new test is now done using touch screen.
