# Transformations

For open ended questions, it is not possible to guess the correct answer. For closed questions (multiple choice) there is a certain gambling chance. For each correct answer to a question, one point is counted. When answering a multiple choice question incorrectly, 1/n point is subtracted from the total number of correct answers, where 'n' is the number of choices for that question.

The final percentage is then the number of points divided by the number of questions asked. This system also applied in the assessment of university exams and is called 'negative marking'.

#### For example

A test consists of 20 multiple choice questions, where every question 4 has answer possibilities.

Someone takes the test and answers 5 questions wrong. It result of the test is then calculated as follows:

15 correct answers = 15 points
5 incorrect answers = 5 x ¼ = 1.25 points
Total = 15 - 1.25 = 13.75 points

The test result is then: (points) / (total number of questions) x 100% = 13.75 / 20 x 100% = 69%

The test result is always rounded off to whole percentage points!

You can use Drillster to choose from the following transformations: .

Name of Drill with matching level
This ensures that if a participant has a certain level. This is retrieved by means of the drill name. Think of A1,A2,B1, ect.

One to ten, proportional to the number of correct answers
This displays the score in a range between 1 and 10 without decimals.

Please note: this does not take into account the gambling factor and the weighting per question.

One to ten, with decimal, proportional to the number of correct answers
This displays the score in a range between 1 and 10 with 1 decimal place. Hereby is taken into account via the account language settings or the is a comma or a decimal point.

Attention: this does not take into account the gambling factor and the weighting per question.

Displays a score of the percentage of correctly answered questions (0-100%)

Attention: this does not take into account the gambling factor and the weighting per question.

Weighted percentage of questions answered correctly
Displays a score of the percentage of correctly answered questions (0-100%). Here it can be set that some questions have a heavier weighting.

Please note: this does not take into account the gambling factor.

Report card grade based upon 60/68/70/75/80% cutoff
The figure is expressed in digits (1, 1½, 2, 2½ ... 10), if 0% is achieved the participant gets a 1. The participant gets 60, 68, 70, 75 or 80%, depending on which transformation is used, then the number 5.5 is linked to it. 100% is transformed to a 10.

Based on the standard testscore.

Report card grade description based upon 70% cutoff
The figure is expressed in digits (1, 1½, 2, 2½ ... 10), if 0% is achieved the participant gets a 1. Gets the participant 70%, depending on which transformation is chosen, then The number 5.5 is linked to this. 100% is transformed The figure is expressed in digits (1, 1½, 2, 2½ ... 10), if 0% is achieved the participant gets a 1. Gets the participant 70%, depending on which transformation is chosen, then The number 5.5 is linked to this. 100% is transformed into a 10.

This figure is then converted to the next Dutch quotation:

• 9½ / 10 Uitstekend
• 8½ / 9 Zeer goed
• 7½ / 8 Goed
• 6½ / 7 Ruim voldoende
• 5½ / 6 Voldoende
• 4½ / 5 Zwak
• 3½ / 4 Onvoldoende
• 2½ / 3 Ruim onvoldoende
• 1½ / 2 Slecht
• 1 Zeer slecht

This does not take into account the gambling factor and the weighting per question.

This function can only be used in Dutch.

Pass at 55/60/68/70/75/80/85/90% (inclusive) of questions answered correctly
This transforms the score to "passed" or "failed" (in the language in which the user's account is) based on the number of correctly answered accounts questions compared to the total number of questions. If the percentage 55, 60, 68, 70, 75, 80, 85 or 90% or higher, is "passed" to the user, If the percentage is less than 55, 60, 68, 70, 75, 80, 85 or 90, then "failed" is awarded. The choice between 55, 60, 68, 70, 75, 80, 85 or 90% can be made by the transformation with one of these six percentages to choose.

Attention: this does not take into account the gambling factor and the weighting per question.

Pass at 80% (inclusive) of questions answered correctly per drill
This transforms the score to "passed" or "failed" (in the language in which the user's account is) based on the number of correctly answered accounts questions compared to the total number of questions. If the percentage 80% or higher is per drill, "passed" is awarded to the user, If the percentage is less than 80% per drill, then "failed" is awarded.

#### Example

A test that includes 2 drills, the user got 90% on the first drill and 79% on the seconde drill, the user will got "failed" for this test.

Let op: hierbij wordt geen rekening gehouden met de gokfactor en de weging per vraag.

Pass at 80% (inclusive)
This transforms the score to "passed" or "failed" (in the language in which the user's account). If the percentage is 80% or higher is "passed" is assigned to the user. If the percentage is lower than 80%, then "failed" is awarded.

Based on the standard testscore.

Qualified at 80% (inclusive)
This transforms the score into "Qualified" or "Unqualified". (in the language of the user's account). If the percentage is 80% or higher is "Qualified" is assigned to the user, is the percentage lower than 80%, then "Not qualified" will be awarded.

Based on the standard testscore.
