This is what Professor Sahab has mentioned on his Facebook page regarding the issue :

"Just few days before my one student inform me about the discussion of new rule of FPSC and showed me a thread of CSS Forum on his Cell. In that thread my one dear student mentioned the new rule of FPSC with the tittle of "Topper": "PERSIAN OR ARABIC SHOULD BE ANSWERED I...N THE RESPECTIVE LANGUAGES UNLESS OTHERWISE DIRECTED IN THE QUESTION PAPER". If it is true then how much it will effect? We can divide all the questions of paper I and II of CSS Persian into two parts: Questions which will not suffer by this rule and Questions which will suffer by this rule. QUESTIONS WHICH WILL NOT SUFFER: Two questions of MCQS (40 marks), Two questions of translation Persian to English or Urdu(40 marks), Make Persian sentences from Verbs or Idioms (10 marks), Two Essays (20+15=35 marks), One question of translation of an English or Urdu paragraph into Persian (15 marks). QUESTIONS WHICH WILL SUFFER: Remaining 3 question of 60 marks can be suffer: Q.2. Of Persian paper I, Write short notes on any TWO of the following in English or Persian(10+10=20 marks). Q.3. Of Persian paper I, Write a detailed note in English or Persian(20 marks). Q.5. Of Persian paper II, Yeki az mataleb-e-zir ra be zabane Inglisi sharh daheed. (20 marks). These 3 questions based on limited topics which you can prepare easily with the help of a teacher who really know Persian language."
