What do you think of this Bible Study?

I just received the book “Christ’s Mother and Ours” by Fr Oscar Lukefahr and a workbook. This Catholic Home Study program was recommended on one of the posts. Before I start this Bible study I would like to know what you think. Is this sound teaching? They offer several others and I would I have been wanting a Bible study program. I’m just trying to be careful. Your input would be appreciated. Thank you.
