5. Pass Rates on various modules
While there is no disclosed rule of thumb for pass rates for each module, it has been observed that it typically hovers around ~43% for CT4, 6,5 and 8. The number is relatively higher for CT1, 2,3 and 7 at ~66%. These stats are for the IFoA. The ones for IAI are slightly more daunting unfortunately (which often discourages students from taking exams with the IAI). For most CT exams, the passing rate has been a little above a third of the students taking the exam. It gets progressively harder to clear some of the later exams with the IAI, especially the SA exam as well as some of the STs where people have noted the pass rates to be a seventh of the total number of students appearing for the exam.
