There are lots of things happening in CS:GO matches, so you might have no time to stay calm and practice aiming and shooting. But it is a worthy training that will pay off nicely.
You have three options:
- Start the game on community-created maps specially dedicated to aiming. Just search for aim training on the Steam Workshopand try out any map you find interesting. Make this CS GO training your regular practice.
- Play with bots and try to concentrate only on shooting. Keep the other important aspects aside for a while.
- Play the Deathmatch mode – it’s a very good practice of fast shooting.
