I agree. Skipping grades and boarding school tends to be a poor combination in my experience. It takes a VAST amount of maturity to live away from home. Every child who has skipped thinks they are mature and can handle themselves. Until something happens. Being 2-4 years younger than your classmates is a terrible social set up imo. Remember that at many schools almost 1/3 of the class are repeats already.
That being said repeating 8th at Groton might be an option if you’re admitted. The kids who have done that really loved it from what I know. However, this class is small and heavily favors siblings of current students.
Have some serious discussions with your parents, or a trusted adult, about sex and drugs before you go to BS. you need to be prepared for how you’re going to handle those situations and conversations with your peers. There is an extraordinary amount of freedom at these schools and kids fill that time…
