Because I've always thought it, well, not that big a deal, but a wee bit wanky, maybe because I only know people who already spend a ton on their DCs education and then pay for a tutor on top.
And now I am considering it for one particular subject myself. (For a DC in state education.) I can't really afford it, but it would only be for a limited time.
So, tutoring: is it a legit top-up to their regular education, or a sharp-elbowed way of shoving your pfb to the front?
