Email support@sigmaprep.io. If it is about a worksheet, include the worksheet's title and the version number printed on the answer key, so we can rebuild the exact sheet.

Sigma Prep Worksheets in ChatGPT

The plugin finds a worksheet topic and makes a printable PDF of new problems, with a separate copy that includes the answer key. It is free and needs no account.

  • Ask in plain words, for example "make a factoring trinomials worksheet with 15 problems".
  • Every request gives a new version. Ask for the same version number to get the same sheet again.
  • There is a limit of 30 worksheets an hour for each person. More options are on sigmaprep.io/worksheets.

Found a mistake?

Every answer key is checked by a program that solves each problem again, but if you spot something wrong, tell us at support@sigmaprep.io with the title, version and problem number.
