Actuarial society of south africa exams

I do not understand how people can write the same exam more than 3 times and fail with an FA and FB and the body keeps failing this person. With acturial exams the pass rates shift depending on how everyone else has performed. Is there a certain number of people that should pass? Is it not obvious this person has enough of the book knowledge and they are very knowledgeable of that subject but just mess up little when it comes to exam technique. If we are real, in the job market if I do not know something I will just Google , go back to my text book or consult. Honestly it gets discouraging and raises eyebrows because you see it feels like a racial thing to an extent Or a thing of making the qualification seem harder than it is. Review and revisit these thresholds. I feel they are not right. It's okay to have over 70% of people that wrote the exam pass.
