I think upsc has been setting questions to dismantle the coaching industry which has become a form of discrimination against the poorer candidates. While many are whining about the randomness of questions, we have to accept that exams like 2020 prelims becomes a leveller for all, irrespective of economic background. It seems prelims 2020 was more about the coaching centers than candidates themselves..
At the same time, the coaching jaggernaut is smart. Am sure it will try to adapt to the changing ecosystem. Candidates will still make a mad rush to coaching centers because of the deep rooted belief the way to success in cse is through the tightly packed rooms in mukherjee nagar.
Many of us are just collateral damage in this game of catch up between upsc and a money minting business.
As for now, am sure upsc is immersed in all its sadistic pleasure.
