To merge two question banks, you must first save one of the question banks to your hard drive. The saved question bank is merged into the other.
To merge:
Open a question bank in the Question Bank Editor, or upload a saved question bank file (.qu) from your hard drive. This is the question bank into which you will merge the other question bank.
Click Upload.
Click the Browse button.
Navigate to the source file on your hard drive. Click Open.
Click Load to upload the question bank. The topics of the uploaded question bank are appended to the list of pre-existing topics in the left panel.
Once the question banks have been merged, you can use Move up and Move down to reorganize the topics in the final question bank.
To backup the new question bank, click Save Work or Install.
