I do not claim to be an authority on the subject. My only qualification to write this blog is that I could actually secure a good rank in the exam. This is going to be a general blog and I am writing answers to the questions which have been asked from me many times (without missing to add general gyan from my side too). I also plan a blog for something specific on mains but that shall be later.
1. Strange it may sound, but there is no ‘secret’ to succeed in civil services. It is only hard work, and more importantly done in the right direction. Do not go for many ‘strategies’ to succeed. Cover the entire syllabus, read standard books, give equal weightage to all the subjects and the chances of your succeeding will double.
2. Coaching is not necessary but it does give you an edge, provided you are at the right institute. But that is the case mainly with humanities . In technical subjects I really doubt if good help is available. Remember most of the teachers for civil services in Delhi are those who tried for civil services four times, failed and then started a coaching.
3. Do not take an attempt to see the paper. Your chance of succeeding at any stage without complete preparation is naught. Also it shall be a better idea to buy an unsolved; you may actually see more papers, than by sitting in the exam unprepared :)
4. Do not try to find statistics that chances of success in which attempt are maximum. I have met many candidates saying ‘third attempt is the best attempt’. The person who guided me, made me believe it is possible in the first attempt and I tell you the same.
5. There are no right optionals . It is seventy five percent interest and twenty five percent availability of resources. The only advantage of a popular subject is that resources shall be easily available . Also since the number of candidates appearing from a popular subject shall be more, good number of students will succeed from that subject hence popular subject remains popular.
6. For those from technical fields ( specifically my friends from IIT’s); you also can take humanities. It was not that you were bad at humanities so you took science after high school, but it was that you were good in science too and more opportunities were available there. Considering the education standards in India, you need not worry that an arts graduate will be having an advantage having studied them for years.
7. Another thing for IITians. Since you cracked JEE, you did not get the birthright to enter civil services by taking science subjects. Before opting for them, make sure that you are really interested in the subject. Times have changed and UPSC has revised their syllabus a lot, from what I hear somewhat on the difficult side. A good amount of hard work is required in them and getting marks in science subjects is linear, that is directly proportional to the effort involved.
8. When I say that I do not mean that getting marks in humanities require less effort. It is that writing style, language etc which play an important role in any humanities develop over the years, so it is your previous efforts in life which makes it appear, that humanities require less time for preparation.
9. Above all, the exam is really difficult and not completely predictable. Do not enter it if you are not very serious about it. It ruins the career of many youths. Remember only 474 guys selected out of nearly three lakh applicants. So if we compare the input and output, civil services is not a very attractive career option.
Ignore this if you find it irrelevant. There is no empirical evidence to all this and it is only what I feel. By the way, if you are preparing for the exam, best of luck :)
