Paper was not tough just a bit different, it could easily be solved. This time Paper1 might be a bit less scoring as I got 87 last time but II can be much more scoring which could brace your total to a soaring level

My views are bit different as per my perception paperI will be high scoring straightforward and simple paper it was as compared to paper II i am saying it by seeing "hawayyan" on the faces of candidates as paper II was distributed. To me paper II was tough. In a satisfied way i just write 2 question pragmatism and logical positivism and the remaining two i attempted was below average in my perception this is the case with all students in examination hall. every body was waiting "pehly koun uthay"

It is the perception of examiner that matters, and when he would witness every paper with below average answers then the one who had attempted it quite well can cross 80s barrier in Paper2 which is indeed a rare thing, secondly it was mainly based on Western philosophy which is always higher scoring, I bet you can never cross 70s barrier by attempting all questions from Muslim portion, however well you might write !!!..
