Just to add to Drewski's comment, ignore anyone on here who comes on and starts talking about you needing 'VR 5 and NR 3', for example. The required marks are available to the AFCO staff only, and can change from week to week. Also, there isn't a direct read-across from you doing a test with sections of 10, 15, 20 questions and the single digit marks you'll be given; it's calculated by a computer programme so you'll have no idea how you are doing as you go along - not that you'll have time to think about that, you'll be too busy!
