Just a few comments I have learned along the way after reading various separate Bible students organizations websites and comments by others about them, they are not organized as one large group sharing the exact same beliefs. These groups are separate, autonomous with varying beliefs: some adhere closely to the Studies in the Scriptures--Russell, others accept some but not all the beliefs from that time, and some even have moved away completely from the teachings of Russell. But most do cooperate in some way organizing conventions, exchanging public speakers, etc.
I have not ever been a Bible Student, but my grandparents were. I have talked to various individual Bible Students from separate groups. Most have never ever been jws; most are second and third and fourth generation Bible Students.
Some groups have buildings for worship, others meet in private homes. Some focus on preaching to others but not door to door. I met some that have a very extensive bible study program with individuals all over the world through the internet and develop members who are willing to move quite a distance if they are not near a group. Some are small groups in a home, others have purchased old church buildings and renovated them for their own use.
Except for the group that broke off in Rutherford's day, these are the only groups I have that have some roots or connection with the WTS some time in their distant past. Bible Students disavow the WTS and connection; they do not consider themselves jws (name Rutherford adopted in 1931, long after these groups came into existence, and none adopting WTS/JW beliefs).
I'm sure some of my comments will not be what a Bible Student might say; my perspective is different having never been a Bible Student.
I invite you to check some of the websites above and form your own picture from secular sources, ex-jw sources, and Bible Student sources. I even met with a nearby small group but realized that not all Bible Student groups have the same approach to making converts or belief system. So I remain independent in my beliefs still.
I invite you to use Google to find the various sources on this topic like I did about 15 years ago. There is still a group still near me now, but their approach was too narrow and too small and invited individual authority over others.
Edited: My grandparents left in 1931 after Rutherford antics but never associated with another Bible Student group after that. They tried later to see if they wanted to become jws; but rejected that idea and made their own belief system.
