I am getting,
1 page for test 1 sub test 1,2.3
halve a page for test 2 sub test1,2,3
quarter of a page for test3 sub test 1,2,3
with around 10 omissions across the whole test, is this good or bad?
That will be fine by the sounds of things - seems like about what I got in the end. Obviously it depends on how big the grids you do are!
