These are partly skills that must be covered in the school exams, but they can also be tested in the Central Written Exam. Until 2010 computers with software were used in the exams to test those skills. Modelling is still included in the exams, but now not as a computer exam anymore. Below you will find examples of exam assignments that can be made with the computer. The models have been translated as well as possible into the current version of our Coach 7 software and follow the original specifications. You can use them to prepare for exams and school investigations and to practice modelling, data processing or video measurement. These examples of exams are used with the permission of the CITO (Educational Assessment Organization in the Netherlands).  ### Large Grazers Year: **2009**Level: **VWO** A model looks at ways to regulate the size of the deer population in the nature reserve ‘Oostvaardersplassen’ in the Netherlands.   - [Assignment (docx)](https://resources-cma-science.com/activities/en/biology/Compex/Large%20grazers/Large%20grazers%20-%20assignment.docx) - [Correction (docx)](https://resources-cma-science.com/activities/en/biology/Compex/Large%20grazers/Large%20grazers%20-%20correction.docx) - [Large-grazers (Coach 7)](https://resources-cma-science.com/activities/en/biology/Compex/Large%20grazers/Large-grazers.cma7) ### Functionaning of the kidneys Year: **2009**Level: **HAVO** This model lets you explore the process of urine production.  - [Assignment (docx)](https://resources-cma-science.com/activities/en/biology/Compex/Kidney/Functioning%20of%20the%20kidneys%20-%20assignment.docx) - [Correction (docx)](https://resources-cma-science.com/activities/en/biology/Compex/Kidney/Functioning%20of%20the%20kidneys%20-%20correction.docx) - [Functioning of the kidneys (Coach 7)](https://resources-cma-science.com/activities/en/biology/Compex/Kidney/Functioning%20of%20the%20kidneys.cma7) - [Correction (Coach 7)](https://resources-cma-science.com/activities/en/biology/Compex/Kidney/Functioning%20of%20the%20kidneys%20-%20correction.cma7) ### Black-tailed godwits Year: **2008** Level: **VWO** The black-tailed godwit population is in sharp decline in the Netherlands.
