Printing for a group?
The batch download puts all 2 tiers' January 2000 sheets in a single PDF, each tier behind its own divider page - 62 sheets in one file.
Every sheet in January 2000
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.
