1. Very first reason of my failure is improper preparation. I did not prepared any subjects completely and effectively.
2. Second reason is lack of writing practice. Due to this reason i could not attempt fourth question properly , almost of all papers.
3. Third reason is related to selection of wrong questions while attempting papers.
4. subject selection is also a blunder for me because firstly i opted British History but in December i replaced it by Indo-Pak.
5. Fifth reason is very amazing that i could not apply my guess during exams and try to revise full syllabubs. But most of the questions came from my guess areas. i only opted my guess in Geography and this paper was outstanding of my all attempted papers.
InshALLAH next time i will cover my all mistakes and appear in exam with full preparation in 2013. Best of luck for those who will appear in 2012.
