Following on from the rest of the sound advice I would add the following:
When doing your faster elements (emergency stop, hazard avoidance) DON'T GO ABOVE SECOND GEAR WHEN GETTING UP TO SPEED!
This is one change too many and over complicates things.
In addition, when you come off the throttle IMMEDIATELY after going through the speed trap, you have the benefit of engine braking to assist you with your emergency stopping.
This same engine braking will mean you carry out your avoidance manoeuvre at a much reduced speed making it easier and less severe.
DO ask the examiner what your speed was after your first go through the speed trap, it is allowed and knowledge is power.
If at all possible, get to the test centre an hour before so you can watch earlier trainees doing it for real. When you see someone pass who clearly isn't as good as you, it is a real confidence boost.
8 months ago, I was in your shoes. I passed both Mods first time (Monday and Friday like you) and now wonder what all the worry was about.
I WISH YOU THE VERY BEST OF LUCK
