Hello, I've just been given my training entry date which is mid next year, I'll be joining as an AET, however I first have a couple questions! In the letter I have just received it says I'm joining as an AET 2nd class? How does this differ to 1st class? Or is that a stupid question?! Also do any of you know any ways that I can give myself the best preparation I can for the training course? My fitness doesn't really need to be worked on, I have that nailed I think I may just get a little more stuck on the technical parts! Also what things will I do on PRNC? How can I best prepare for that also? Thank you!
