@ enigmatic
it seems that you have made it a habbit of getting confused in your subject selection first it was political science now its muslim law
anywayz coming back to the topic

Musliam law gave alot of marks last year...most of the students who appeared got 60-70 and some even 72-75.But it depends upon the examiner in 2006 many students failed in this paper and this year too the paper was not according to last years pattern it means the examiner was changed now lets wait and see what the students get

international law is also not difficult and also not lenghty. Respected Miss sarah scored 90/100 in css 2006 in that paper there were two problem questions on diplomatic immunities (on the pattern of university of london law papers) so that is the reason students were able to get such marks.another respected member of this forum sohail_pk scored 84 that year but the in 2007
the average scoring range was 45-60. but this year the paper was very easy and straight forward much like a paper of LLB-Part2

In the end what you have to do is go through some question of both.it shouldn;t be a problem for you as you have completed you llb.on which ever you think you can have better command go for that.As at the end what helps is your knowledge we shouldn't be thinking about the scoring factor as it keeps on changing every year
