Getting better at the game

I suck, how can I be better? I want to become SMFC or better I am not sure

As someone said long time ago, for you to get better at something, you need to practice more.

It is easy train everyday and shoot people in modes and ezpz xd

Uh, I could tell you to watch tutorial videos. But personally just train your loved one, and learn the maps by heart (strategic side the player placement or where to place his grenade for exemple )
