I did my RT in Barton. I imagine if your Lancs based that may be an easier option for you (?)
Took a 5 week course which basically went through a basic script.
On test day, you are given time to prepare. Route where you may need to cross a MATZ, divert and have a Mayday/Pan (think I had engine failure)
Just take your time, scribble down some notes before you make each call and taking a coin in to trace your route helps too!
