Hi Nara,
Welcome to the board.
The 2 persons who give you the study, do of course not see it as a cult or high control organisation, and they give you study because they think it is in your best interest.
So they do not try to trick you or something deliberatrly. They are mostly honest and mean every word they say.
They will tell you probably that yi will get some oppsition from family and friends. (as noted above).
When you are doing well, they will ask you to join to them to the kingdom hall for the meetings.
Then if they really think that you know enough, like almost finished the book, and you join all the meetings they willl ask you to go into the field service (door to door). And then the baptism.
Most studies do not make it that far. Maybe 1 in every 100 or so.
what is good to do is ask questions and see how thety react.
