Sanskrit is a subject which has been known for scoring thorught the life of a student ..but yet we find very few takers of Sanskrit in UPSC . The main reason being lack of reliable materials in the market and over advertisements of sucess of other subjects . After much enquiry I did research into the Subjects and syllabus and here are the findings .
1> The sylabus is small and limited [ Means there cannot be a total surprise in the question paper . One has to just write what he is prepared on] .
2> Sanskrit is scientific , if u already learnt Sanskrit ..you would have realised this . Thus much scoring . Infact It has given some aspirants as high as 450 .
3> Every year there are some people who have cleared with Sanskrit like Sharat , Ritu etc of recent . [ Best part is u can directly speak to them to know the pit falls]
4> After speaking to Sharat , I got the reference of Dr Rajendra Kumar who teaches Sanskrit for UPSC .He is a nice gentleman who is ready to help aspirants to great level . He can be reached at 9818559711 . [ This is for the benifit of aspirants , not for telemarketers] If you are a aspirant and seeking some serious guidance then he is one of the best option . He has maintained notes which is a contribution of his students who have cleared UPSC via Sanskrit . I have the copy of notes [ hard copy not digitized] .
5> Genrally one has studied Sanskrit more than Geography or other subject ..
I hope this provides some insight into Sanskrit for UPSC .
