During the test, you can recognise an invalid input (input that cannot be interpreted by the system). The invalid input is marked by the yellow/orange mark on the left side bar or at the overview sheet by the text 'invalid input'. Those answers will still be stored by the system, but not automatically graded, and the grader will grade that answer (manually).
During the practice and test, you can recognise invalid/incorrect input. It is marked by the yellow/orange mark on the left sidebar or on the overview sheet by the text 'invalid/incorrect input'
'Invalid/incorrect input' is the text the software shows when you enter an answer that is considered to be an incorrect formula. In other words, an answer that doesn't exist in the language of mathematics.
Examples include:
- A bracket that is out of place or doesn't close, such as 5+6(
- A double exponent, such as 5^^3
- An answer template that isn't filled out completely
You should always give answers in correct mathematical formulas. However, trained mathematicians will grade your final and mock exams. In the case of incorrect/invalid input, we will, therefore, still be able to grade these types of answers. In most cases, we are able to see what you intended and grade accordingly.
