I don’t know english at all, though I can speak, read and write, but how can I improve my speaking power, as am good at speaking but doing grammer mistakes?
Speaking is the last skill to develop, and depends on doing much reading and especially much listening. Don’t worry about the grammar mistakes; they will either fix themselves or remain ingrained habits for the rest of your life.
I don’t know also speak and read and write very well because I don’t use to much This is not good you have to use every day and find peopel who speaks in English This is good for you
