Grading schemes provide a means to map achieved percentages to a numeric grade. In the current versions, a fixed number of 5 grades is supported.
A grading scheme consists of a grounding scheme and grading boundaries. - A grading scheme can be selected at exam definition time - Lecturers can define their own grading schemes and reuse these between exams - Available grounding schemes: * no rounding (recommended for small exams, e.g. 5 minutes or 2 points) * by percent (the calculated percentages are rounded to the provided number of digits) * by points (the calculated points are rounded to the provided number of digits) - The grounding precision can be defined by the user (e.g. to 2 digits) - The grading boundaries represent percentages boundaries necessary for a certain grade - When selecting no grading scheme, no grading information is provided in the exam protocol (just percentages)
More changes: - allow grading also, when student has not submitted the exam - added percentage information in the grading-box (esp. useful for composite questions) - renamed predefined grading schemes to more neutral terms - provide easy-to-type names for question-manager, answer-manager and form-loader - new utility for more robust list-comparions - defined validating form-field type for grading boundaries
