I am a Driving Instructor.

Whilst learning to drive you should have covered dual carriageways, so you already have a bit of experince in that area.

Pass Plus will teach you some finer points of driving thta you wont necessarily have covered whilst learning to drive.

To be honest, its not essential to do it, just a good idea if you can.

Check with your insurance company before doing it to see if you get a discount - some do it, some don't.

Biggest discount one of my pupils had when we done Pass Plus was £900, on a Corsa SXi
