I am in a great confusion in deciding my optional subject for civil service exam. I am an above average student in maths with a great love towards it. I have gone through the syllabus and found that the syllabus is almost similar to the engineering maths syllabus ( I am a BTech Electronics graduate). I asked many institutions in delhi about this. Some institution told me that the subject is one of the toughest in civil service exam and most importantly the Normalisation (multiplying factor used to multiple with the actual mark u got in optional) is very less. So they suggest that it is a risky optional. Please let me know all the possible pros and cons regarding maths and it would be nice if i get the best coaching available also.
