I don’t want you to waste time wondering how you can improve your English. By reading an English book(choose your favorite one) You can set yourself up reading a few lines or let’s say one paragraph at first if your reading skill is just at the beginners’ level. Try to master that one paragraph for a week and What I’m trying to say here is that you perfect each word, the pronunciation, punctuation on each sentence, vocabulary, definition and intonation.
Try silent reading and reading aloud. This will improve your fluency.
