I found there are some contradiction between workshop output and use case description in my part 2 assignment. The use case description can't fulfill the given requirement. If I follow the use case steps, I will lose some very important output requirements. If I don't, I am afraid I will breach the flow of the given use case, I might lose mark for that. So, How should I do? Have you ever faced this type of situation during part 2? I'll appreciate your replies.
