9/10 - thank god.
I'm having refresher lessons at the moment because I passed my test as a teenager and haven't driven since. I thought I'd be OK to drive, we hired a car, and then my girlfriend caught me whispering 'OK, now, left to right, accelerator, brake, clutch, oh, no, maybe it's the other way around' and point-blank refused to be in the same car as me unless I got some lessons.
Seems like I still have a fair knowledge of the highway code, though!
