You want the assistant to answer from your course, not from the open internet. Attach your collections first. Then it looks up passages in those files and builds the reply from what it finds.
Attach your materials first
Open the assistant and go to its knowledge base. Link the collections that belong to this course. The assistant can only look up resources that sit in those collections.
Wait until a resource is Ready. While it is still processing, waiting, or in error, that file is not reliable search material.
How the assistant finds an answer
Raison does not paste every document into the reply. It searches the attached collections by meaning and by keyword, then feeds the most relevant excerpts to the assistant. You may see a short searching state while that lookup runs.
Those excerpts are the source of truth for course questions. The assistant is told not to invent facts or citations. The reply is built from passages, not from a full copy of each file.
See which files were used
When an answer cites course materials, the latest reply shows Sources. On an older reply, open the extra actions and choose View sources. Compare the reply to the cited passage.
Learners see those sources only if you left resource sharing on for this assistant (it is on by default). That control lives in learner experience settings.
When it can look outside the course
Your files stay first. Two optional settings can widen the search after that, if your organization allowed them: general knowledge as a fallback, and web search on a given message. Learners turn web search on per question. When it is off, the assistant cannot search the web for that turn.
If both are off, and the collections have nothing on the question, the assistant should say it does not have the material, rather than guess.
A file a learner attaches in chat is not the course knowledge base. Notes in the notebook are the learner's. Where they disagree, the knowledge base wins.
