hello:) if you wanna improve your English you can find friends who talk English fluently~ and who help you about it^^ and also if you want you can download App like, Duolingo* i think this App the best for you to improve your English hehe

You can think about what you want to learn English for. Once you know that, you have a smaller task to tackle. If you want to learn English for work, you will want to start with the kinds of things you'll need to communicate in a work environment. If you want to be able to read English novels, you might want to focus on reading. Once you know that, it might help you see what you need to learn and develop. Good luck! :)

The correct phrase is, "What should I do to improve my English?" You can compare your original question with this correction, and start from there. :)
