Your welcome :3
Yeah we do xD We start from Pre-school ( which isn't really a grade.. ).
Then when we enter school it's Kindergarden, Year 1, Year 2, Year 3, Year 4, Year 5, Year 6 then that's primary/middle school finshed :3
Some high-schools are different to others here. Some only go up to Year 10 and some go up to Year 12 xD
