1. Why don't they give you your preliminary results as soon as the test is over? Certainly, the computer "knows" whether or not you have passed or failed as soon as the test is over. So many people that I know have endured tremendous unecessary stress waiting for the results.
2. Why, have questions that are harder than the minimum passing standard? Since you don't get "extra credit" for being able to answer the "top tier" questions why even ask them? Why, should certain canidates have to answer questions that are harder than passing level simply because they can?
