Cs exe dec 12 mod 2

Dear all Just to clear my doubt,i have cleared cs exec mod 1 in jun 12 after 2 attempts with exact 150 marks and i have a bad habbit of self evaluation after every exam. In the self evaluation process for jun 12 mod 1 after giving min marks for every question for example max 3 to 3.5 marks for the 5 mark ques. I got 157 and the result was 150 pass.In dec 12 i appeared for mod 2 and again after self evaluation it is about 158 ....REALLY CONFUSED...one more thing..I am working in a stock broking firm for abt 5 years as Asst manager -equity..what are the career prospects after cs. Plz reply ...thanks in advance.
