Well it depends how long you have been playing..

I was rubbish when i first started.. a few months later im a god at it!
well perhaps not

but certainly better when i first started,

its just simply, 'practice makes perfect'

keep at it, and you'l get better, try 'Create a server' and playing with bots, getting used to maps and the guns and you will build up a good knowledge of the world of CSs!

Good luck to you, hope i helped a bit
