Thank you so much for replying and answering my question. I certainly understand it's not a credited course.    

I am from Japan and English is my second language but the lessons have been no problems so far.  I was hoping someday there will be this kind of study in Japanese. I imagine it would be a lot of work.  

I do listen to the Japanese broadcasting and use a lot of the materials from BBN for our weekly Bible study with the same group of people.  Thank you for what you do for Christians like us and for our Lord. May God richly bless you and the ministry.
