7 of 8 when I first took it, IIRC (it was late 2016). I just retook it and got 8/8.

So off the top of your head, you knew the percentage of under one year olds vaccinated against measles +- 10%, global electricity availability +- 10% and the global rate of primary school attendance by girls +- 10%? Do you work in public health?

Yes. And no. "Knew" is too strong for some questions; "had a good idea" is closer. I could easily have gotten 5/8 or 6/8 (or 8/8) initially.
