Well I passed the test this morning, the truck they took me out in had the stiffest clutch I've ever experienced in nearly 20 years of driving manuals. But like was said, the guy was like "if you can drive this, you can drive anything".
I haven't driven a vehicle without power steering for over 15 years so that took a bit of brute force, as did pressing down on the clutch.
I clipped a kerb with the back wheel when making a turn because of the dodgy steering and drove a bit too close to the kerb a few times but otherwise did enough to pass.
