Tooba last year, I too joined NUML in order to improve my language skills. During the whole semester they taught their prescribed syllabus of four skills named Writing, Speaking, Listening and Reading. Frankly speaking, their way of teaching or syllabus,etc. was not satisfactory at all. As far as Grammar is concerned, I can suggest you that the basics like word classes (parts of speech), Tenses, Translation skills and a short introduction to Active-Passive & Direct-Indirect Narration are well worth including. I think within a single month,they can easily be covered.
