I never really noticed this - I was in a gifted program here, and the birthdays were split pretty evenly across the classroom. There were slightly fewer birthdays later in the year, but close enough to even (probably no more than 3 or 4 kids in a class of 25~) that there wasn't an exceptional difference.

Also, in all the classes I took there, there was no real notable difference in intelligence/capability levels of the olderish kids to the younger ones. I was one of the later ones, being born in late september, but my average was consistently in the top 5 every year.
