I like to send students out the door with a good understanding of PivotTables. They're much faster, more accurate, and more tolerable than writing conditional-aggregation-function (RACON) formulas.
Here's a link to a (roughly) 10-minute video by Kenji that shows you the kinds of things I'd like students to know.
And here are links to a practice worksheet and answer key Google AI and I built to allow you to practice those PivotTable skills.
