The mod1 is known as "the difficult one". I think nerves are the killer, because it's easy to go round some cones and do a u-turn in practise but the sight of a clip board gives you enough of a wobble to make it tricksy! Keep your head up and good clutch control and jobs a goodun. Mod2, stick to speed limits, lifesavers lifesavers lifesavers and don't hit anything and you should be fine The first time you get on the bigger bike and feel the acceleration it will be terrifying but soon becomes easier going at NSL as the bike is more stable than a smaller 125, and you're not subjected to as much wind buffering.
