I also think we can discuss doubts etc here only. I appeared with philosophy in mains 2020. But got less marks than expected. After going through Himanshu Gupta’s answers for paper 1, I think my main problem was lack of “content density” (or basically use of a lot of keywords). I also may not have fully addressed the demand of the question at some places. I couldn’t study philosophy for last few months for some reason. Now I am updating my notes with better content and trying to appear for tests regularly. Still have to figure out what went wrong in paper 2.
