I am working on Part II of the certification and came across with a question about the sequence diagrams. Do we need to provide diagrams for just the use cases that we have details or do we need to provide diagrams for the others as well (e.g. create profile, log in, etc.)?
I think the number of sequence diagrams depend to a large degree on your design approach. In my case, to avoid cluttering the diagrams, I provided more than the 4 sequence diagrams needed and a got all the alloted marks for the sequence diagram. Just be confident in what you are doing and explain yourself as good as possible
