You can start by joining the Kick Off Association... Whereabouts in Norway are you? We have some Norwegian members and improvement would come more easily if you played against human opponents.
You can check our Improving Your KO2 Skills
A good advice would also be to download our latest competition version
, a hacked version of Kick Off 2 (same gameplay, don't worry) that will give you many more options, such as practice free kicks.
