The MB-820 certification is coming for Business Central developers. In this article, you will find helpful guides for each certification requirement. This will give you clear, step-by-step guidance to get ready for each part of the certification.
Just a note: I’ve gathered Microsoft documentation, learning paths, and a few of my blog posts. Keep in mind that these are not official training materials for the certification and some of the points might differ from the actual requirement. But they’re a great place to start your learning journey.

That’s it! There is already an official GitHub repo for practicing:
MicrosoftLearning/MB-820-Business-Central-Developer-Certification (github.com)
That´s all. Hope you find it helpful.
Thanks a lot for this great overview!
I just took the (beta) exam for which my preparation was largely based on your overview. It was a great help and I am quite positive regarding the results which will come in a few weeks. *fingerscrossed*
I am very experencied in the areas covered in this exam, but took a number of days to follow all links and took all learning paths mentioned.
Very important to know is that you are allowed to use Microsoft Learn website during the exam. The result of my preparations is that I am now “very good” at navigating the learn website which was of great help during my exam.
During the exam I used this strategy.
– please note that the exam consitst of multiple parts, and that after each part you have to confirm you have finished it completely. ( so make sure you have reviewed your answers).
– I tried to answer every question (per section) from personal knowledge / experience
– every answer I was not 100% sure I marked for review.
– during review I used learn to validate my answer ( this turned out to be a good strategy since subsequent questions are often related to eachother, in some cases answer for 3 questions on one learn page)
Thanks again.
Very valuable information and feedback. I hope more developers can pass the exam with all the info we can gather.
Thanks for sharing!
Thanks for sharing this amazing guide! Navigating Dynamics 365 Business Central might feel tricky, but your ultimate guide gives clear help and important tips for new developers. It’s a great help to the community!
Thanks!
Can you do some extensive guide for MB-800 ( consultant) certification too? I would like to get the certification and where we can do some mock tests that actually reflect the real exam.
thanks for the idea!
