Personally I think the online exam should be kept as open book as it helps deepen their knowledge and invites them to continue the habit of searching 

I ask for 10 case studies and invite students to buddy up so they have support in their learnings 
Once they have completed all 10 case studies one of which I will speak to client (with their permission) and find further feedback. I schedule an appt with student to go through each case study 

3.Not sure about additional fee structures 
Have things changed since Germany and there will be experts.? Is this the same as specialists ? 

I think exam should be reinstated immediately as several of us are going through workshops and it looks highly unprofessional to change something so fundamental mid syllabus
