"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."
