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**

*Please note: this is for adaptive tests only.*

**One to ten, proportional to the number of correct answers**

*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**

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

**Percentage of questions answered correctly**

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

**Weighted percentage of questions answered correctly**

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

**Report card grade based upon 60/68/70/75/80% cutoff**

Based on the standard testscore.

**Report card grade description based upon 70% cutoff**

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.*

#### Please note!

This function can only be used in Dutch.

**Pass at 55/60/68/70/75/80/85/90% (inclusive) of questions answered correctly**

*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**

**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)**

Based on the standard testscore.

**Qualified at 80% (inclusive)**

Based on the standard testscore.
