Backcourt on throw-in

[Raymond]

A1 throw-in from frontcourt base-line. B1 deflects throw-in in f/c followed by A2, with f/c status, deflecting ball which then goes into backcourt. Can Team A retrieve the ball in the backcourt? Is there a difference between NCAA or NFHS since in NCAA there is team control on a throw-in?

I know that in both rule sets that if B1 deflects the throw-in A2 cannot jump from the f/c, catch the ball in the air, then land in the b/c because the throw-in ended when B1 deflected the ball and thus the b/c exemption would no longer apply.
