First 6 years.
And I must confess...I didn't really care for it. Coming from a family that didn't practice, I wasn't really pressed to take much of a real active interest.
But no...We didn't have any bibles for any kind of bible study. Of course they were available, all over. Just not "Studied" like I've seen other religions do.
But then again, maybe that's common for the first 6 years?
Well if your family didn't practice, then it would be hard at that age. But yes, starting in the upper grades the Bible was studied, not to worry. Like I said, the early years are religious education/instruction to set the stage. There was always a emphasis on Jesus.
