# Match text pattern¶

Use a text pattern part when you want the student to enter short, non-mathematical text.

## Marking¶

Match test

The test to use to decide if the student’s answer is correct.

• The Regular expression test checks that the student’s answer matches the regular expression given in Answer pattern.
• The Exact match test marks the student’s answer as correct only if it is exactly the same as the text given in Answer pattern. Space characters are removed from the start and end of the student’s answer as well as the answer pattern before comparison.

The text or pattern the student must match.

When Match test is Regular expression, this is a regular expression defining the strings to be accepted as correct. If there are several valid answers, separate them with a | character. If you’re using the full regular expression functionality, note that ^ and \$ are automatically added to the start and end of the answer pattern to ensure that the student’s whole answer matches the pattern.

You can substitute variables, the same as in content areas, by enclosing expressions in curly braces, e.g. {answervar}.

A representative correct answer string to display to the student, in case they press the Reveal answers button. You can substitute variables by enclosing expressions in curly braces, the same as in content areas.
Must the answer be in the correct case?
