IAS Mains Optional: 4 Things to Avoid

  1. “My Friends and Family have suggested it.”
Do not choose an optional because a friend or a family member suggested it.
2. Most students opt for it.” Do Not opt for an optional just because it is what most of the aspirants have chosen. Believe it or not many serious candidates fall prey to this and waste attempts before they even realize it and still many realize it after exhausting their attempts.
3. “Its a high scoring IAS Mains optional” Candidates have cleared this exam with almost every optional  and not just with the so called high scoring optional. In UPSC there is no high scoring-low scoring optional but only a paper, an innocent examinee and a ruthless examiner. High scoring-Low scoring optional is a myth.
4.”The topper chose this subject last year”  Don’t let your judgment be guided by the optional chosen by the previous year toppers. Probably they topped the examination because they did not base their choice of options on the subjects chosen by still past toppers.
