well.......new rules by FPSC read....
" The Question Papers in Urdu or other Pakistani regional languages (Punjabi, Sindhi, Pushto and Balochi), Persian and Arabic should be answered in the respective languages unless otherwise directed in the question paper"
so it means in 2015 there would be no more English option as well.....one has to attempt in Persian....so to attempt history questions and poetry explanation in Persian is really a difficult task..................
but different people interpret this rule different....and some argue that there would be option of English as well.

Authentic interpretation is required
