I would like to add a bit on that. One can always choose to skip Logical Positivism, Pragmatism as well as Subcontinent Muslim Philosophers. In their entirety. You will be safe even if the pattern of the paper is changed (like it did this year). If someone wants to do these topics, s/he can skip some other parts. Going through past papers gives a pretty clear idea of what to leave and what not.

After skipping optional parts, the syllabus of philosophy is less than many, if not most, other optional subjects. At least this is true when we compare it with the history subjects.
