This is what I did, went to test centre a few weeks before MOD1 and saw the layout and watched a couple. I did my A2 licence on my own varadero 125 without any training, just a years riding experience. Failed MOD 1 first time, passed it 2nd time. All I can say about that is have a go, if fail, you will be more than ready for 2nd time round. They tell you where you go wrong, so know what to do for 2nd go if need it. On MOD 2, is pretty straight forward, if been riding around on a 125 for a while, do same on that just remember to do everything by the book. Which leads me onto my biggest help to pass MOD 1 and MOD 2, "Learn to Ride" Book, has so much information in it and helped me loads. Give it a look.
