I would definitely recommend revising the examples at the end of Safety sense leaflet 22 (
Safety Sense Leaflet 22: Radiotelephony | Publications | CAA) as some of them bear an uncanny resemblance to my RT test!
If you're confident with your RT already, you may not need any practical training, but an opportunity to practice using the exam equipment may help as it's not at all like a real radio.
Good Luck
