RT terrified me at first and I was convinced every time I spoke I would just sound like a blithering idiot (my wife says that's normal) So I bought an air band receiver and when travelling around I would tune into various frequencies and listen to the experienced aviators - I soon learnt that they were no different to me! In general I let the receiving party know who I am, where I'm from, where I am at that present moment, where I want to go, how high I am what QNH I'm on and what service I want. It can also help to use little post it notes with the relevent calls already written (just fill in the blanks) and tear them off your knee board when you've made the call. Most importantly, I found that "Say again" is a call that will allow you to take more time in understanding what's being said. I have found most ATC's more than helpful and if you mention that you are a student they will make an extra effort. Just remember to clear up all the post it notes when you land
