Answers come from your course book. Not from the open internet, and not from someone else's notes.
You can check every answer
Each answer shows where in the book it came from. Tap it and you land on that passage, so you can read it yourself.
Do check, especially before an exam. The book is what you are examined on, and it is right there.
When the book does not say
If your course material does not answer the question, you get told so rather than given something that sounds right. A confident wrong answer about your own syllabus is worse than no answer.
When that happens, try a wider choice. A question This passage cannot answer is often covered elsewhere in the unit or the course.
What it is not for
It answers questions about the course you are reading. It is not the place for questions about registration, TMAs, exam dates or your student record.
For those, tap Chat with Idara on your home page — that is exactly what Idara covers.
If an answer looks wrong
