Union Public Service Commission [UPSC] — Language

Language
Language plays key role in clearing UPSC..in preliminary exam[objective type] firstly you have to understand what they have given so that you can choose the right answer, in Mains you have to write extraordinary answers to get good score over the other candidates it is possible only when you have good command over one particular language.

UPSC exam papers will be in two different languages one is English and the other one is Hindi.

Let me tell you one example:

I am from Tamil Nadu and my mother tongue is Tamil as I am not good/known to Hindi I must completely rely on English (colonial language) so here I have to be too good in English to clear UPSC why I said too good is if you observe the UPSC mains questions you will understand the difficulty.. sometimes if you don't know the meaning of a single word you won't be able to understand the entire question then how will you write the answer to that question??

One person from the north (UP/Bihar) their mother tongue is Hindi and the UPSC paper will also be in Hindi means he need not to be good/rely on English..we should accept one truth here, everyone may not be so perfect in any other language but every individual(educated)will definitely have good command over their mother tongue.

Above picture shows the UPSC preliminary CSAT paper) For me the left side one is some other language not my mother tongue but for a UP/Bihar candidates the same passage(right side)will be in their Mother tongue.

This is also one of the main reason that people from South India not showing interest in UPSC as candidates from many rural areas are not so comfortable with the English. At the same time it is very difficult for upsc to provide question papers in all 8th schedule languages so it is one of the disadvantage for the non Hindi candidates.

Qualifying nature of CSAT(General studies paper 2)
General perception(almost true) is North Indians are extremely good in General studies part than the CSAT(aptitude/English) but South Indians are good in CSAT compared to General studies.

So many candidates from the north agitated against the CSAT paper and demanded to scrap the CSAT… so UPSC changed the pattern in 2015..They converted CSAT as just qualifying paper (candidate need to get just 66 marks out of 200) so they consider only General studies paper 1 marks to decide whether he/she qualified for preliminary exam.

IMO the candidates who relied on CSAT marks are now hopeless in qualifying the prelims so they are not showing any interest in UPSC rather they are concentrating more on other private sector jobs.

In UPSC Hindi known candidates are definitely have some advantages over non Hindi candidates.

Views expressed above are my personal not to offend anyone. I don't have any North/South feelings. I love India n love to serve any part of the country n sorry if I hurt anyone.

EDIT: I am not against the Hindi speaking people I love Hindi and i'm trying to learn Hindi but we have to accept one fact here that

For a Hindi speaking, English medium candidate there will be two choices either English or Hindi.
For a pure Hindi medium candidate there will be at least one choice that is Hindi(if they don't have good command over English)
But For a pure Telugu/Tamil/Kannada/Malayali medium candidate who don't have good command over English, do they have any choice?? {As I said earlier to clear UPSC, candidates should have extraordinary English[writing n understanding] skills}So Simply they will concentrate on state services or they will try to get other jobs.
.

I didn't say that language is the only reason I did mention it as one of the reasons.
Some one commented like “ Hindi also had tough words n it's actually not helpful to English medium candidates (Hindi speaking) n most of the students rely on English”. And someone said “ Hindi translations are very tough that even pure Hindi medium candidates are not able to find it as easy” If this is the reality (if Hindi language is not really useful to any medium candidates) then what's the need of having Hindi in the UPSC question papers?? If most of the candidates rely on English then Let's just have only English (it's not possible for UPSC to conduct exam in all the 8th schedule languages) I welcome that move by the UPSC then at least it will be equal-equal for all Indians. No North/south/west/Northeast feelings.
