Congratulations from me too.
Now Masters, I've seen it described as a Police Advanced drive but without exemptions.
So, that'd mean commentary throughout and no overtake within NSL missed, together with no question about car control.
You can go for a drive on your own and try this, then decide whether you would want to try for Masters.
The most important point about all this AD stuff, which I hope you have already realised, is that safety is the paramount point, your's and others'.
If you decide to not continue with anymore AD stuff but internalise your learning from the IAM First and apply it in your driving you'll be better than the majority on our roads.
