Hi,

The Databricks Certified Generative AI Engineer Associate exam information page mentions that there is a series of self-paced courses in Databricks Academy.

You can login to Databricks Academy from this page: https://www.databricks.com/learn/training/login 

Once you log in, search for "Generative AI Pathway" using the form at the top:

 That learning plan includes the four classes that you will have seen mentioned on the exam info page:

• Generative AI Solution Development
• Generative AI Application Development
• Generative AI Application Evaluation and Governance
• Generative AI Application Deployment and Monitoring

The self-paced courses are free. I hope this helps!
