An answer key is wrong
Send the worksheet's web address and the question number. Answer keys are the thing most worth getting right on this site, so these are fixed first, and the sheet is pulled if it cannot be fixed.
A question has two defensible answers
Grammar has real grey areas, and a question that admits two answers is a bad question even when the key is not exactly wrong. Tell us which sentence and we will rewrite or remove it.
You need a worksheet that does not exist
Tell us the grade, the skill and the topic. If it is something other people will want too, it goes on the list. In the meantime, the custom generator will usually build it for you immediately.
You want to use the worksheets somewhere specific
Classroom and home use needs no permission. Anything else — a school website, a printed workbook, a tutoring service — ask first and we will usually say yes.
