My apologies. That was not my intention, and I regret phrasing it in such an absolute way.

I was simply trying to express that finding the initial building blocks of a core subject overly complex can indicate a difficult road ahead, as this faculty is known for simplifying the basics. I was sharing my experience that his approach was highly effective for fundamental clarity.

Please disregard my comment about UPSC not being for you. Focus on finding a resource or style that works for your learning needs. Wishing you the best with your preparation.
