Practice for the conditional totals unit, on a library's loan records. Each task names what to find; you choose COUNTIF, SUMIF, the IFS versions, AVERAGEIF or MAXIFS, and write the conditions.
Watch the argument order. SUMIF and AVERAGEIF put the range to add or average last; SUMIFS, AVERAGEIFS and MAXIFS put it first. Put text in quotes, comparisons in quotes, and join a cell to an operator with &.
