You can print or save quiz reviews (ie, quiz questions and answers) and peer assessments you've received. For quiz reviews, visit the quiz page, click 'Review' next to any of the attempts you have made, and use the print or save feature in your browser. If you have a PDF writer installed (such as CutePDF), you can print the review as a PDF file.
For peer assessments, visit the peer assessment activity page, view the assessments you've received, and use the browser print or save feature. Alternatively, you can manually copy and paste the assessments into a document. Also see: how to view the assessments you have received
