She has a good knowledge of the English language, I can carry on a conversation with her, She is just using the wrong grammar. She has been improving in class. Using what she has been learning, she does apply it in conversation. If she continues in her growth she will do well.
Update: She has been improving, and retains what is being taught and applies it to her sentence structure. She is an asset to the class, because she is always asking questions about improving her English, She has been doing well on using all new and correct words.
