Should I repeat 9th?or apply for 10th

@Happytimes2001 in my very limited experience with BS, what you’re describ No is typical. DS was a true, non-repeat, 14 y.o. Freshman last year. He came from an independent K-8 school and had no reason academically to be held back; and where would he have gone. We wouldn’t have sent him to our mediocre public HS for a year and then gone through the BS process. However, at a school with a big sports culture, DS is young and small among his friends and teammates. Although he played varsity last year, he was the youngest and may still be the youngest as a sophomore. Many kids go to public school through 9th or even 10th or 11th and then go to BS and repeat — it’s very common especially for kids hoping to be recruited. One of DS’s friends is a junior who just turned 18 — he came in as a repeat sophomore last year and probably started kindergarten when he was turning 6, so he’s basically 2.5 years older than DS (and a high ranking prospect). I think DS’s class started with 45 freshmen and will be close to 100 at graduation.
