Have downloaded some of the pdfs ( like 01_-_Beer_Stabilisation_part_1 and 02_-_The_function_of_wort_boiling1 ) but didn't find 04, 05, 06 Are these the pdfs you are refering to?
BTW: What was the cost of the exam?
Ref. the blog. Write to IBD and tell them what you intend to do - after all, until you sat this exam no-one here knew of the IBD so you have already interested some potential students like me.
The blog would publicise the course and encourage people to sit the exam. It would be like a "blog tutorial" ("blogatorial")- It would also really help those studying the exam to discuss such short commings as you have just pointed out and to clear up their confusions
Good luck
Will
