Driving assessment

My dear Hubby has to go for a driving assessment for the DVLA to see if he can get his revoked licence re-issued. Has anyone had to go for one of these and if so how long did it take?
This should help:

Thanks very much Ray that is very helpful :smile: I'll print it off and show it to hubby. Sure it will take some of the mystery out of things for him
