Assessment only on Friday
Ok then, well...
Shooting falls to the marksman, and the day, paralax of the earth, moon and sun etc etc

Just hope your having a good day and the rest will fall into place.
The "Saftey stalk" is straight forward common sense, apart from if they have the little wooden deer actually painted as the real things so you have to ID, season and decide if safe to shoot.
The Deer Recognition, depends on the question disc they are given to use that day, but 20 pics, up to a minute each. Take your time, breath... Make sure you have a system for narrowing it down and then make your choice. They only want the species naming and then a tick in the male or female column.
Large Meat Hygiene is 40 questions out of the known question bank on the DMQ website etc.
I sat the lowland DSC paper, 50 questions, and again, straight forward if you know the answers
Advice wise, be brushed up on seasons, law, meat hygiene and just stay relaxed. No point going into the exam a jittering mess and flunking answers you know. Once you've finished, stop, read through the paper again and make sure you have at least had a go at all the questions, I nearly left 2 blank which would have slimmed my chances obviously.
As long as you are prepared and revised, there are no surprises, I'm sure you will be fine.
Good luck
