Imported grades must match one of the fixed list of valid grades, as follows...

• 100%
• 90%
• 80%
• 75%
• 70%
• 66.666%
• 60%
• 50%
• 40%
• 33.333
• 30%
• 25%
• 20%
• 16.666%
• 14.2857
• 12.5%
• 11.111%
• 10%
• 5%
• 0%

Negative values of the list above are also permitted.

There are two settings for this switch. They affect how the import routine treats values that do not exactly match one of the values in the list:

• Error if grade not listed
  If a question contains any grades not found in the list, an error is displayed and that question will not be imported.
• Nearest grade if not listed
  If a grade is found that does not match a value in the list, the grade is changed to the closest matching value in the list.

Note: some custom import formats write directly to the database and may bypass this check.
