Book your place and Dave will send you a book ! read the book read it again and again untill you go on the course . 
  
Practice your shooting prone,kneeling and standing off sticks. 
  
Then attend the course and Dave Strettons team will guide you through your level 1, they are a great bunch. But unfortunately i could not spare the time to attend the full course and just did my assesment there, and had a great day in good company. 
  
I suppose good luck should come next BUT if you put the time and effort in you will pass.
