Running a study group that actually turns up

What sharing actually does

Sharing a reviewer hands a copy of it to the people you share it with. You own your material and can delete it, but once a copy has been given away it stays with the person you gave it to, which is why it is worth being deliberate about what you share.

Groups work the same way with more people. A group gives everyone one place to see the reviewers that belong to it, rather than a private link that expires or a chat thread full of attachments nobody can find again.

Set up the group before you share anything

The thing that makes a group work is a name that means something to everyone in it. A group called Test Prep 1 will be abandoned. Name it after the module or the paper.

Then agree two things before the first session: who edits shared reviewers, and what happens when someone gets a question wrong. Those two questions are where groups normally go wrong, and agreeing them up front costs five minutes.

• One person edits questions and answers; everyone else reports. A group where five people rewrite the same reviewer produces a reviewer nobody trusts.
• Corrections go in the reviewer itself, not into the chat. A correction in a chat message helps nobody who was not there that day.
• Shared reviewers are drafts until checked, exactly like generated ones. Treat anything in a group the same way you treat an AI-generated question: verify it against your own material before revising from it.

One shared reviewer per topic

The failure mode is four people making four reviewers for the same section. Nobody wants to be the fifth, and the group ends up with more material than anyone would revise anyway.

Make one reviewer, share it, and improve it in place. Because Hachi records when the questions of a shared reviewer are edited, the people using it are told the material changed rather than quietly revising an older version.

Use the session for the hard part

Meeting up to each person reading a reviewer alone is a worse version of studying alone. The time is worth spending on the things a group is genuinely better at: arguing about which answer is right, splitting a topic up between people who each take a section, and covering the parts nobody has read yet.

A structure that works is a short individual attempt first, then the group session working only through what people got wrong. The individual attempt gives everyone something to contribute, and the group does not waste time on the easy half.
