 But I want to and you appreciate this aspect of preparation. See, and I have been industry for almost 21 years of teaching, and my own preparation for four or five years. So that's go to 2526 years in UPSC career. That's quarter of a century, a long time, I believe. In this entire span, what I noticed is questions have changed. The syllabus has changed. The type of reading material required has changed. The explosion of issues around us. Awareness has shot through the roof in terms of time has not changed. Back then when I was studying, also GS was, okay, one year approximately. Now also one year. Then geography used to take about three and a half, four months. Now it takes five months. Okay, the course in terms of the time has not changed. And then also the classes were two and a half hours on average every day. The same thing you guys are doing more or less. The problem is the teaching pedagogy, the approach, the teaching methods, the teaching, you can scope. Well, that has not changed. The questions have changed dramatically. Think of a question like this. Okay, one question is, I'm giving a gender equation. I'm assuming you all know this. Okay. What are the prospects of solar energy in India? Discuss its pros and cons. Let us question. Discuss solar energy as a game changer in India's energy security and of major support for small marginal farmers. I hope you get the question One question is, what is solar energy? Prospects and pros and cons. How is it helping us? How not helping us? Okay. And the second one is, I've asked something else. I've asked you about, tell me how is it a game changer in terms of India's energy security? And then I'm asking you, tell us if this can be a major support for small marginal farmers and how and realize the difference of the content here required typically in class, a teacher teaching and even you studying. If I ask you, tell me five things I teach in solar energy. Most of you will tell me, tell us what is solar energy? What are the technology? What are the prospects? What are problems? What are solutions? Most will say, sir, you want the structure and we teach that. But the questions have gone to next level. So while I cannot afford not to teach the base content, but the base content is not anymore. Yesterday I took a class. I'll show you some questions also on those. The question was on give us your opinion on is India doing enough to manage energy based geopolitical challenges for India's economic growth? Is India doing enough to manage energy based geopolitical issues, challenges for India's economic growth? You realize where the question level is. I'm asking your opinion. What is India doing? A, B, C, D. Tell us is that helping India in terms of energy geopolitics? I won't even ask you in terms of energy security. But when I'm in the class teaching you guys, I will teach you from where India gets oil, gas, what are the problems, what we have done recently and that's all. This question is at a different level. So you must appreciate that in your preparation now at least last three, four years, your preparation has to go through some stages. You're like, you know, go on walk and run and fly the stages. Earlier the base content used to be enough. The base content taught in eight, nine, 10 months was enough. The questions have driven particularly after 2017-18 and the chain had started from 2014 onwards. So I'm talking about
