Getting into 11th grade is notoriously hard for the “elite” boarding schools.The struggle you went through for high school could be a hook of some sort.I agree with cababe97 100%. In my opinion you should just stay at your local public school for sophomore year but still apply as repeat for 11th grade.You have a okay chance though like said earlier getting into 11th is hard and many highly qualified applicants get rejected each year definitely for 11th.You should also if you have time,read chance posts from 10th grade applicants to see what your competing with and get a feel of how hard it is to get into boarding school. Are you applying for financial aid or are you full pay?
