DDs approach may sound hard, but you need to remember the FI us the front line of training. Our industry for some bizzare reason allows the most inexperienced to teach the new intake, therefore it's imperative that you are preperaed in full.
Although you will never use most of the stuff you learn in those questions, they are great food for thought and your FI Instructor will draw from them for your teaching presentations.
Enjoy your course.
