Wouldn’t it be wierdos, not wierdoes? My autocorrect seems to think so.
Also in the UK, where I’m from, we have standardised testing, when i was a kid the tests were all made by exam boards like AQA, OCR and EdExcel. I believe they still are.
Despite the flaws that come with that it was better than allowing an individual to come up with the test as it removed personal bias and, obviously, derogatory remarks about students in the class.
