Prince Luthra (UPSC CSE AIR 577)

Hello Aspirants, I am Prince Luthra (AIR 577) from UPSC 2014 batch. I started the UPSC preparation way back in 2010. I was giving my time, effort, and energy. I was pretty sure to pass the exam in 1st attempt but I could not. After the failure, I asked myself why could not I clear prelims? After a lot of analysis, I figured out that I was reading the books toppers told me to; Nevertheless, in the prelims exam, I was making mistakes in MCQs. I started attempting MCQs for preparation. This strategy worked since when an MCQ is asked then your brain stimulates and starts searching for answers. Our MCQs series capitalize upon this concept and hence we provide you Spectrum MCQ series and Laxmikanth MCQ series so that you score 90-95% in History and Polity MCQs which will take your marks above cut off be it UPSC, PSC, EPFO or any other exam. This strategy helped me clearing Prelims of UPSC and UPPCS, I am certain that it will help you too. All the best! Prince Luthra (AIR 577)
