# Count Responses With Syntax Errors As Incorrect Submissions for Assignments

When question part submission is allowed, you can choose whether or not to count responses containing syntax errors toward students' total submissions. You can configure this separately for numerical, symbolic, or algebraic questions.

When assignment or question submission is required, syntax errors are always counted as incorrect submissions.

Syntax errors can occur in responses to numerical, symbolic, and algebraic questions, and often include the following kinds of incorrect notation.

Question Mode | Problem | Incorrect Notation | Correct Notation |
---|---|---|---|

Any | Incorrect grouping operator. | 4{x+3} | 4(x+3) |

Any | Missing operand. | 50* | 50*3 |

Any | Too many consecutive operators. | x++++2 | x+2 |

Any | Unrecognized symbol. | .00 4&6 | 4.00 4+6 |

Numerical | Misspelled unit. | 3456 met/sec | 3456 m/s |

Numerical | Response cannot contain variables. | 2*x+3 | 2*10+3 |

Numerical | Response cannot use implicit multiplication. | 3(14) | 3*14 |

Symbolic or Algebraic | Comma in number. | 5,000 | 5000 |

When your students submit responses containing these kinds of errors, a message is shown indicating either that the response contains a syntax error or cannot be evaluated. If you are using question part submission and do not count syntax errors as incorrect submissions, your students' used submissions is not increased for question parts with syntax errors.

By default, new assignments do not override the class settings for syntax errors.

The default class settings do not count syntax errors as incorrect submissions when question part submission is used.

You can change these behaviors for your classes or for your assignments. Your assignment settings override your class settings.

If you must change a scheduled assignment, notify your students of the change and rescore the assignment. See Rescore Assignments.
