Turn a score into a band without nesting IFs
Four thresholds, one readable formula. The nested-IF version is where bracket-counting errors come from.
The data
| Row number | A | B | C |
|---|---|---|---|
| 1 | Student | Score | Grade |
| 2 | Ava | 92 | |
| 3 | Liam | 78 | |
| 4 | Mia | 64 | |
| 5 | Ethan | 51 |
Your task
Put a formula in C2 that returns "A" for 90 and above, "B" for 80 and above, "C" for 70 and above, and "F" otherwise.
Your formula goes in C2
The checker compares your formula against the accepted answers — it does not run it. The expected result is shown with the solution so you can verify it in your own spreadsheet.
Why this is the right formula
Highest threshold first is not a style preference: IFS returns the first condition that is true, so putting >=70 before >=90 would grade every high score as a C. The trailing TRUE is the "otherwise" branch — without it, a score below 70 returns #N/A rather than "F". The nested-IF version is accepted because it works everywhere, including versions older than Excel 2019.

Questions
Does this actually run my formula?
The checker normalises case, spaces, argument separators and dollar-sign anchors, then compares your formula with a reviewed list of accepted answers. It does not evaluate the formula. Copy the data into your spreadsheet to verify the expected result independently.
Can a correct formula be rejected?
Yes. The accepted list includes several reviewed approaches, but cannot recognise every equivalent formula. Compare an unlisted solution with the expected result in your spreadsheet and use the page feedback if an accepted answer is missing.
