My instructor organised it all for me within a week of asking (in fact booking the test was a 2 minute internet session) so there is not really a long wait time..at least in Fribourg. I paid all my fees in one go when I took the theory test.
For my driving test I did have to go on the motorway. I also had to do a "long reverse" on wrong side of road and parrallel parking. I'm surprised that you had to do none of these things as (in Fribourg at least) they are standard practices.
I'm also surprised you were allowed use a Mobility car (by Mobility that is) seeing as you don't (well didn't

) have a full licence but I never looked into that.
o and congratulations!
