How are Bible studies counted?

Studies are tracked per contact, not per day. To count a study, open a contact, log a conversation, and mark it as "Conducted Bible Study." That contact will count as 1 study for the current month, even if you have multiple sessions with them. To raise your study count, mark a study conversation with a different contact. Visits that came with a contact someone shared with you are theirs, so they don't count; once you log your own study with that contact, it counts.
