I am wanting to know how to find out how fluent i am in japanese anyone know how i do it
Japanese does not, at present, give a fluency percentage; only some courses provide this. You are not missing anything, however, as it is pretty meaningless.
oh now I know it
You have a long conversation with a native speaker and see how many mistakes you make.
This is really the only way. Fluency results determined by a computer program should not be taken seriously.
