I've opted both of them - Pashto and Public Administration.
I think if you analyze Pashto paper all you have to do is to write answers to 2 long questions of 20 marks each, other than that you have 40 marks for translations, and 20 marks for MCQs. Obviously it would consume a lot of time if you go for 3 long questions or 4 long questions and in that case writing speed do matter.
