Ethics paper was first introduced in CSE 2013. Since then the paper has gone a lot of transformation in terms of quality of questions and marking pattern. Initially no one had any idea about how to prepare for this subject as there was no reading material or standard syllabus.
However, things have stabilized now. UPSC has now increased the toughness level of questions and it is difficult to score good marks without studying thoroughly and having a good grasp over the subject.
There are students who still manage to get 100+ marks without even preparing for it. But I would not recommend this strategy.
Here is how I prepared for it. I got a decent 113 marks in the paper.
