These professional exams are known to test the understanding of the concepts and its applications. So in exams, do we need to necessarily reproduce what is given in the study material? Will marks be awarded if we explain certain concepts with content and examples from outside the study material or may be from our own experience?
It never hurts to demonstrate commercial awareness, but the exams test the material in the core reading. If you can't answer a question using it, it is unlikely that something ese would be adequate to get you the marks. It may help in that it may give the examiner confidence to give a questionable half mark here and there but I wouldn't focus on it.
