Common Questions

Frequently Asked Questions

What grading scales does the normalizer support?
Five scales simultaneously: US A–F (with +/−), UK Honours (First to Fail), IB 1–7, a simple A–F (no +/−), and Pass/Fail at 60%. The grade scale comparison table shows all five for any score you enter.
How does the curve adjustment work?
Enter a positive or negative number in the Curve Adjustment field. The tool adds that many raw points to your score before calculating the percentage, so you can model the effect of a curve before applying it to the class.
What is the z-score and percentile used for?
Z-score measures how many standard deviations a score is above or below the class mean. Percentile shows what proportion of students a score would be above. Enter the class mean and standard deviation in the Class Statistics card to activate these.
How do I use the Scale Converter?
If a test was marked out of 60 and you want to express it out of 100, enter 45 (score), 60 (from max), 100 (to max) in the Scale Converter card. Click 'Use this score above' to load the converted value into the main calculator.
Can I normalize a whole class of scores at once?
Yes. Paste or type comma-separated raw scores into the Batch Class Normalizer. Set the max score and grading scale, then click Normalize All to see a full table with percentage, grade, and z-score for every student, plus class statistics (mean, median, SD, min, max).

"The side-by-side scale comparison is genuinely useful for international students who need their grades translated. I paste in a score and instantly see US, UK, and IB equivalents — no more looking up conversion tables."

"The batch normalizer is the feature I didn't know I needed. After every test I paste 30 scores in and within seconds I have a full grade table, class mean, and SD. The PDF goes straight to the department head."

"We compare applicant scores from schools using different marking schemes. The scale converter handles the translation in seconds — much faster than our old spreadsheet lookup tables."

"My son brought home a score of 67/80 and I had no idea if that was good or not. This tool showed me it's 83.75% — a B in the US and an Upper 2:1 in the UK. Couldn't be simpler."
