It mostly boils down to what gun you are using and reflexes. I use a year 2 Monte Carlo or my righteous 7 for its upgraded stability. I recommend you get a righteous 7 since you can get it from high monarchy for 150 marks and learn to use that. Make sure your scope is pointed at there head even if the reticle isn't on them because that gives you a better chance of getting a headshot and let the gun do all the work. It took me about 2 days to learn with my Monte so I'm sure you'll learn quickly. Now I always manage to get 1st if not second place even if I go negative. And don't get worked up over dying because in my case iit makes me do worse. And don't use blink. Never use blink.
