How good are you at Excel, really?

Ten formula questions in a real spreadsheet, from SUM to INDEX/MATCH. They get harder as you go. No sign-up, and you get your level at the end.

• Type the formula in the highlighted cell and press Enter, the same as in Excel.
• Two tries per question. Not sure? Skip it.
• Your formula has to work if the data changes, so typing the answer doesn't count.
