April 2013 5-a-day
Printing for a group?
The batch download puts all 2 tiers' April 2013 sheets in a single PDF, each tier behind its own divider page - 60 sheets in one file.
Every sheet in April 2013
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
