NOT A TEACHER.....
Since I'm Thai and my english is not my mother tongue, I should be qualified to answer this question.
I don't know what grammar syllabus is, but I assume that you are asking what it is that you need to know about grammar when you are the beginner who learn English. It seems to me that you speak English well and your native language is Persian. Can't you answer that question yourself?
If you ask me I would say that learning how to contruct the sentence properly first.
