    Hey, I got 9 right, missed moons of Pluto, but you gave me an 8/10. Looks like you program did not account for the extra 5 question, just the first five since I aced the last 5.

      Hi Terry,
      Thanks for the feedback! Sadly, the quiz changes every time you load it, so I can’t get the same bug to appear. But let us know if it happens again, and I’ll dig a bit deeper.
