And the girls from Maryland are older within each grade just like on the boys side.
Holding kids back works out well for the boys because they tend to develope later. For girls - they all catch up by 8th or 9th grade because that is generally when they are all done growing. Back in 6th grade - a 13 year old is going to be that much bigger than the 11 year olds. But, once the girls hit that "period" in their lives - their growing slows down.
