I've delved in to the bowels of the Quiz Master's ditty bag to arrive at an equitable ruling re. making a mistake with your answers only to realise it later.

Because we all make typos and mistakes (even The Quiz Master)

After consultation with my lawyers this is what I shall do.

If in error you submitted a set of answers which on reflection may/may not be correct.

I'm going to allow ANY quiz entrant to resubmit a different set of answers and specify clearly that this is to supersede any previous submissions, a bit like making a will, declaring all sets of previous answers null and void.

I shall then discard the first set and only mark the second set.

I will NOT mix and match and pick the best from two sets of answers oh no that is NOT going to happen.
