Hi,

I'm also preparing the assignement and feel same way.

I have read some discussion of ranchers, apparantly we are allowed to change in the domain model, the main idea i got, "It's alright to make changes as you make assumptions to explain thoses changes".

You can make changes in the provided BDM but don't change the problem statement totally.
I will say some 20-25% kind of changes are acceptable but if you are changing the whole BDM-you are troubling your chances to pass the exam.
Whatever changes you are making in terms of cardinality etc... always document it and provide the right justifications why you did that and the reason should not be like to make the solution simpler or the team members can't digest this complexity.

In my assignment - i made only one change - change a many to many relationship to one to many and provided the necessary reasons and justifications.
