Doing the exercise once

Hello, If it is one ofyour own worksheets and use custom links, you can tell them it is available up until, say, March 10th or the next 2 hours. Then you'll have to make changes to your worksheet so that the customlink no longer works. If you use workbooks, go to Allow Exercise Repetition" and choose 0. It all depends on why you want them to do it once. You can always tell them you'll take into account the first one you get, which might encourage cheating...

If you use a custom link, you can simply warn them that you will only take into account the first try. If you use workbooks, you can limit the number of times they can do a specific worksheet or the whole workbook. Just click on "Allow exercise repetition" under a workbook or under a worksheet.

Long time no coincide answering the same question at the same time, TeacherARG. :-)
