Characters that can't be graded

When working in a mathPad, calcPad®, or physPad® problem, a message is shown indicating that your answer contains a number of characters that can't be graded.

Unsupported characters might include control characters, symbols, or foreign language characters.

Some common causes for unsupported characters in answers include:

  • Copying and pasting an answer from another source.
  • Using a foreign-language keyboard layout.
  • Typing characters that look like math symbols but which can't be parsed.

Resolution

  1. Delete your recent changes until the message is no longer shown.
  2. Use the pad tools to finish entering your answer.
