**How should I prepare for the case study?**

By the time you get to the case study you will have been tested on a whole range of skills. Some of these will be tested again during the case study but others, like communication skills, will be tested for the first time. 

Our [Data Communication Concepts](https://app.datacamp.com/learn/courses/data-communication-concepts) course will help you prepare to present to technical and non-technical audiences. 

**Can I practice a case study before I book a time?**

Yes! Although we won’t be able to give you any feedback, you can try one of our old case study projects currently on our [GitHub pages](https://github.com/datacamp/careerhub-data).
