Follow through with your shot, meaning you keep looking down the scope and not move your face away trying to see where you hit. Thats what spotters are for.
From a bench, tripod, shooting sticks or off hand you can practice by dry firing with a fired case or snap cap, you'll see if you are getting of target or not. You'll notice If you jerk the trigger, close your eyes, look away or flinch, you will aee some weird stuff and ask yourself, why the heck did I just do that.
Hope this helps and stay safe
