Excel skills you can prove.

Practice real formulas in a live grid. Every answer is graded, then re-run on different numbers, so passing means you can do it at work.

Your first formula, about 30 seconds

Type =SUM(B2:B4) in B5 and press Enter.

Tip: type =SUM( then drag from B2 to B4.

Typed-in numbers don't pass

Most quiz sites check whether the number in the cell is right. We check whether the formula is. After your answer matches, the grader swaps the inputs and runs it again.

Re-checked on new numbersA formula that only works on today's data fails, just like it would in a real report.
One formula, filled downFill exercises need a single formula copied across the range. That's how $ references get tested.
Told why, not just wrongFeedback names the cell and the mistake. Stuck? The tutor explains without giving the answer away.

The task: total the three costs in B5. Both answers show $2,205 on the original data.
Row	Formula in B5	Original data	Rent changed to $1,635	Result
1	=SUM(B2:B4)	$2,205	$2,390	Passes
2	=1450+620+135	$2,205	$2,205	Fails

Watching feels like learning. Doing is learning.

In a classic memory study, people who practiced recalling a passage remembered far more a week later than people who reread it. Videos are the rereading of spreadsheets: easy to follow, quick to forget.
