As others have mentioned, if you have connections to that state it may be worth applying. The stronger the connection the better. Strong connections being, but not limited to: going to college in that state, having years of childhood in that state, having parents live in that state or having worked for a time in that state. Most secondaries for public schools will ask you as an OOS why you want to come to their state and having some personal history with the state makes a much stronger case than the random OOS applicant with zero connections.
