Grrr!
Thought I was way above 80%, so didn't spend much time checking results, even though I had over 20 minutes left.
78.7%.
Rats
But I guess that does show me that there is more to learn.
The big surprise is that (other than Join and Union, where I got only 62.5%), most of my shortcomings were on the more basic tools, like Browse, Input, Sort, and Cleanse!
My higher scores tended to be on the more complex tools. Did not expect that.
Clearly these tools have some features I need to pay more attention to.
Oh well, I'll get it sorted next weekend.
