My tip is to shoot... just shoot... don't be afraid of missing, get used to your sensitivity, animations and overall feel of widow... play as much and as often as you can, in qp don't doubt your shot, don't overthink, just look at your gun, zoom and shoot... you don't have the reaction time to make real time adjustments and you end up having the illusion of thinking about the actual shot (giving you the illusion of complete constious control) when in reality all you use is muscle memory and your brain automatically makes the small adjustments... how do i know this ? this way work all games with guns... you get better at it with time...
