Is this exam hard compared to the rapid developer exam? Any helpful tips? Thanks!
You can prep for the test, but instead I would advise you to become as good a Mendix consultant as possible. Why? Because that is what the tests are actually testing. If you are good and know a lot about Mendix, you will pass the test.
To do that:
Do as much academy trainings of Advanced-level as possible.
Read the forum-posts and to see what problems people run into.
