I didn't think that was too bad. I'm happy with 37, given the text was densigned for beekeepers in the US.
Some of the questions were tricky or irrelevant, i.e. going from celcius to farenheit, converting the months of the year around, km/h to m/ph. When trees found in america flower is kind of irrelevant in Australia.
I, also failed the one about working the bees when the neighbours are having a party. That would depend on how far away your naighbours are wouldn't it?
Next time I shall use a calculator :).
