Annoyingly, if you already have a drivers licence I really don't see the need for this... however we have to do it so there. It's common sense, apart from a few techy questions on stopping distance (I got one)... but pretty easy tbh... I got 47/50 on the day I think... Hazzard test is the same, hard to fail unless you're a retard OR you don't know what you're doing or your mouse button doesn't work lol.
Personally for me, the MOD1 was the toughest as in I was most nervous as it's "foot down = fail" thing keeps you right on your toes.
You've done the right thing, just get it done no, no arsing about next year when it all changes again etc... good luck and keep us updated.
