The best anyone can do is a ‘maybe’. I don’t know if I heard it on here or somewhere else, but I remember someone saying that chancing for boarding school is a lot like dating, and I’ve taken it to heart.
If there is a guy/girl you really like, and if you ask a friend, “What are my chances of them falling in love with me”, the friend can only predict so much. You and look and say, “Well, you both are interested in horses, and you both want to live in Hawaii someday”, but you can’t predict whether they will fall in love or not.
But to answer your question- yes, you certainly have a chance, and you are a strong applicant. Following the advice others have told you will increase your chances! Good luck!
