Best scoring optional subject for UPSC

There are a few subjects in which you can score more than the other optional subjects. Even the experts say that lower marks in UPSC exams are either because students do not answer the questions to full potential or prefer a wrong optional subject.

As per some of the previous year’s trends, technical subjects like Maths are the scoring ones! As the ‘subjectivity remainder’ is quite limited in the technical matters. The non-technical topics, like that of literature, are also based on the examiner’s point of view. Hence, you may score less than that of the technical subjects.

Although some of the non-technical subjects are interrelated to UPSC’s prelim papers, they may or may not be fruitful for you. After all, it comes down to your preparation and potential in that particular subject.
