(Tips) Civil Services Mains Exam: Optional Subjects Selection | UPSC 2010

Choosing the right optional subjects in the Civil Services Mains exam


Choosing the right optional subjects in the Civil Services Main exam will determine your success. Most often, candidates choose their main area of study as the first optional paper. And since a major part of the syllabus is taken care of while preparing for the Prelims, it’s time to deal with the second optional paper which will consume most of your preparation time.

So how do you decide your second optional paper?

Here are a few parameters that will help you decide.
First, you must be interested in the discipline. Evaluate your aptitude to learn the subject; the choice should not merely see you graze through to the next level. Don’t let the length of the syllabus influence your decision. History and geography are known for their notoriously lengthy content whereas public administration and anthropology have the least topics to learn. The secret does not lie in selecting subjects which are short or lengthy but on how comfortable you are in grasping them.

Here’s a litmus test. Pick up any basic book of the subject and read the first chapter.

  • Are you keen to read the next chapter?
  • How much do you recall of what you read?
  • Are you ready to make notes for the next three hours?

Assess these factors and you will know if this is your second optional.

The next vital step is the availability of resources. Find out how easily study material, guidance and coaching are available. If you have studied the discipline then you will have a fair idea about the syllabus and also the source for books. But if it’s a completely new subject then it’s sensible to speak to a senior who will be able to guide you.

Don’t choose a subject because it’s scoring. You may have heard that subjects like public administration, history, geography, psychology and philosophy are scoring but that is not true. Don’t select a subject because your friends are picking it. The UPSC has its own set of rules which puts every subject on a common platform. If there are more students opting for a particular optional paper, say history, then according to the UPSC’s proportional representational rule, more candidates with history will be selected for the next round. Popular subjects will offer more number of seats but not a greater score.

Again, if you are opting for a paper which is easy, remember the easier the paper, the tougher the competition. And last but not least, scan through the last 10 year’s question papers to give you that winning edge.
