Answer

Because you are from Iran, I am assuming that you are looking for Sorani Kurdish. Prof. Wheeler Thackston has a Sorani grammar course that you can download in pdf from here: http://www.fas.harvard.edu/~iranian/Sorani/sorani_1_grammar.pdf. He is the author of the leading Persian textbook in English, so I am sure this must be a good course too :)

He has also made the same course available for Kurmanji.
