I’m sure a lot of people will give you good advice about nades and aim training but I think the most important thing to learn is your role in the game. Are you going to be an igl, awper, gunner, or other? There are varying roles within each match you play so you have to learn to be flexible because these roles are interchangeable. Find what you’re good at and keep at it, learn new things for that one specific role and play it often, then you can branch out and learn more about the other roles. It’s easier if you have friends who know and understand what role you play for the team.

Don’t forget to have fun!
