Notice how I asked how much debt your kid is racking up. I asked that question because I bet you you are tapped out after spending all that money on Prep, which in the end, got him no further than the public school kid he is sitting by in class.
ok-but the OP asked for tuition costs-not dining expenses, rental cars and hotel bills which I'm sure can add up rather quickly if you take the whole family to showcases.
Yes. But Tuition is just a portion of the total out of pocket expenses to play FS 16/18.
Just go in with eyes and wallet wide open.
