The Book Study is one of the most useless meetings. The same books have been studied 3 or 4 times.The meeting takes only an hour but takes up most of your evening. And, it is one of the least attended meetings.
Why haven't they combined the Watchtower Study with just question and answer and then follow with the Book Study with just question and answer? The WTS would still sell their 6 million books but save time for everyone.
