Groups correctly answered

If you have been using the Questions answered correctly feature then eventually all of the unseen questions will be "used up" and this window will automatically open. You can also open it manually by clicking on the edit control next the the Questions answered correctly option.

You can remove groups from this list. If you do so then all of the questions in the group will be used again in tests. If you cancel the window then tests will be available but will not contain the default number of questions and the "seen" topics will not be present. This feature works by temporarily de-activating questions and so an alternative way to remove questions from the "seen" list is via the Contents of question pool feature.
