Speaking is perhaps the skill that most students are concerned about. Unfortunately, it is the skill that it is most difficult for us to help you with directly. Fortunately, because all the four skills are linked, any work you do on listening, reading, or writing will indirectly benefit your speaking ability—even if you don’t feel any improvement immediately.
There are many things you can do to improve your speaking, perhaps the most important being to make an effort to actually speak in class when you have an opportunity. Also, you should do lots of listening practice to prepare yourself for speaking, and do some shadowing practice, too. Try asking your teachers or the LLAs for more advice.
