There are strict rules surrounding photocopying. You can only photocopy a chapter, article or 30%* of any Revision Guide (whichever is greatest) if you have a CLA licence. 

• You can’t use any photocopies commercially e.g. as course materials for private tuition.
• You can’t photocopy any of a Workbook (this is a CLA rule, not ours).
• You can’t photocopy anything if you / the institution you work for don’t have a CLA licence.

* This percentage is currently increased due to the county's current circumstances, but will go back to the normal 5% in due course.
