To me, test was tricky! because quite a as few questions were vague;
ie:primary evidence:: nearest option was docunentary evidence ; but stricktly speaking it should not.
Semilarly three questions in a sequence, about cultivation of narcotics in pakistan and their transportation etc had vague options ; whether they are totally prohibited or partially
Since narcotics are permitted under a licence for medical, scintific or industrial use!
But this was not clarified in questions.
So i believe no one can be 100 % sure of his answers!
