Philosophy verses Public Administration
 

Dear Seniors,
In a bid to choose a common collection of optional subjects for upcoming PMS and CSS exams I am ascertained on the following: Political Science, Constitutional Law, Pashto, and US History.
Now I am vacillating between Philosophy and Public Administration. I have an interest in Philosophy but I fear its length and hence much time consumption. Plzzz guide me about Public Ad; how many days it will take to prepare (I being an engineer); And how much difficult it is as compared to philosophy?
Looking up to your valued responses!

Public Administration is obviously easier than Philosophy.
I have opted both for CSS 2021 so I can tell that you should only go for philosophy if you are good at understanding and remembering a philosopher's arguments/concepts, and can reproduce them in the paper in a coherent way.
Public administration is more about memorizing stuff, although it has some theories but they are way easier and nothing complicated like philosophy.
Go through the past papers of both and just read some content from any introductory book of these subjects. You'll get a good idea from it.
