As others have said don’t rush, doing level 2 is nothing like doing level 1, you need experience, if you have shot a lot of deer successfully before you took your level 1 fair enough go for it, if not think again.
To gralloch a deer, find and identify the lymph nodes ect successfully takes practice, esp when it is dark and raining ect. I personally had shot hundreds of deer before I did my level 2 and still had to concentrate to get it right, that leaves aside stalking your deer successfully in the first place, while this part can be made easier by doing it in a park.
I would read up on level 2, understand exactly what you need to do to gain the award. Then spend a year shooting as many deer as you can solo, do every stalk and gralloch to the level 2 book, once you are clear in your own mind that you know exactly what you are doing then go for level 2. Remember that you will need to pay your assessor for every stalk successful or not, the average stalker in Scotland at least will shot a deer 1 stalk in 3, if you don’t get it right it could cost you thousands of pounds.
In the past I have taken out clients who despite having shot plenty of deer would have no chance of doing a level 2 stalk and gralloch successfully.
Most of all enjoy the sport, it is not a competition.
