The UK CAA has produced the following standards document for potential candidates over here. I dont know how much things differ in Ireland but its all supposed to be one European wide umbrella so things should be pretty similar (tongue in cheek?)

Your Instructor should give you a good run down and a mock test beforehand but in any event I'm sure your examiner will brief you thoroughly on the day and if you are unsure of anything said then don't be afraid to ask - its often far more dangerous if you assume!
Good luck for your test!
