The second part of question 3 caught me off guard - lost a lot of marks there. I also could not make good progress with the calculation of the Var and TailVar in the last question - 8 marks... As usual, I ran into time trouble. Overall I think the paper was more difficult than the previous ST9 exams.
Does ST9 have the same broad pass requirements than other ST subjects, i.e. something around 50%? Or is the requirment tougher due to the CERA qualification that comes with it?
