Printing for a group?
The batch download puts all 2 tiers' June 2012 sheets in a single PDF, each tier behind its own divider page - 60 sheets in one file.
Every sheet in June 2012
The same date always regenerates the same five questions, so a sheet you print today is the sheet a classmate prints tomorrow.

- 2nd June 2012A youth club has 45 members under 13 and 75 members aged 13 to 17 (120 total). A stratified sample of 40 members is needed. How many aged 13 to 17 should be sampled?
- 3rd June 2012A different table shows test scores out of 5 for 30 students: 1 (freq 3), 2 (freq 5), 3 (freq 9), 4 (freq 8), 5 (freq 5). Find the mean score.
