My DD sat the last paper that was taken in Jan (I think 2007)
I have a feeling it was 115 but not less than 120 in two of the three papers. Please feel free to correct if wrong.
That sounds right for 2007. Pass mark for each paper was 120, aggregate pass was 360, but were allowed to "fail" one paper providing the score was not less than 115. Jan 2008 was a slight variation on the theme but I cannot recall the numbers precisely, might have been 117.
The aggregate pass has remained at 360 though over the years.
Also the various numbers in the posts above do not illustrate the actual pass scheme. Sometimes only one failed paper, ie below 120, was allowed, other years it was two providing the aggregate score was 360.
It should also be remembered the changing pass scores do not indicate a rise or decrease in the actual raw scores required. The changes are only really a slight tinkering of arbitrary scores, no doubt to "manufacture" the correct number of passes.
