How to Choose the Right Optional Subject for UPSC Mains

Choosing the right optional subject for the Union Public Service Commission (UPSC) Mains examination is one of the most crucial decisions an aspirant needs to make during their preparation journey. Despite the weightage of the optional subject being reduced to two papers of 250 marks each (totaling 500 marks out of 1750), it can still be a game-changer and significantly influence the final rank in the merit list. Many toppers owe their success to a well-thought-out choice of optional subject. But the question remains – how should one go about selecting the right optional?

This blog will help you break down the process by understanding the key factors you must consider before locking in your optional subject for UPSC Mains.

Understanding the Role of Optional Subjects in UPSC Mains

Before diving into the selection criteria, let’s first understand why the optional subject matters so much.

It contributes 500 marks out of a total of 1750 in the written exam.
It allows candidates to leverage their strengths, especially if they have a background in a specific subject.
It can act as a differentiator in case General Studies scores are very competitive and tightly bunched.

While choosing an optional subject may appear daunting, with careful introspection and analysis, it can become a strategic advantage.

Key Factors to Consider When Choosing Your Optional Subject

1. Interest and Aptitude in the Subject

The most important factor is your genuine interest in the subject. You will be investing several months of preparation, reading and revising the subject multiple times, and writing descriptive answers in two exhaustive papers. If the subject does not engage you mentally, you are more likely to lose motivation mid-way.

Ask yourself:

Do I enjoy reading about this subject even outside the exam context?
Can I sustain interest in the subject for long periods?
Does it naturally align with my strengths – writing, analysis, memorization, logic, etc.?

For example, if you’re analytically inclined, subjects like Philosophy or Anthropology may suit you. If you enjoy reading history and stories of civilizations, then History might be your calling.

2. Availability of Resources and Guidance

Even the most interesting subject can become a nightmare if there are no good quality study materials or mentors available. Check the following:

Are standard books and notes available in the market or online?
Are there coaching institutes or mentors who specialize in that subject?
Are toppers’ answer copies and strategies available for this subject?
Can you access mock tests or peer-review platforms?

Subjects like Geography, Sociology, Anthropology, PSIR (Political Science and International Relations) have a wealth of resources readily available, making them more accessible for first-time aspirants.

3. Scoring Trends and Performance in Recent Years

While no subject is inherently “scoring,” some do witness fluctuating performance trends based on how UPSC frames the questions. Observing past trends can help identify how predictable or unpredictable the paper has been.

However, do not get swayed solely by trends. A subject that was considered “low scoring” might suddenly become the favorite of the next batch. Focus on consistent performance over multiple years rather than just the last one.

Sociology, Anthropology, PSIR, and Geography have generally shown stable and strong performances in recent years, but this is not a guarantee for the future.

4. Overlap with General Studies Papers and Essay

This is one of the most strategic considerations for aspirants. Some optional subjects have a high degree of overlap with the General Studies syllabus, helping reduce the overall preparation burden. For instance:

History, Geography, and Political Science are widely covered in GS Paper 1 and 2.
Sociology and Ethics may contribute to GS Paper 4 and Essay.
Philosophy and Psychology can also provide good content for Essay and Ethics.

Overlap can be a huge bonus, especially for working professionals or those starting late. However, don’t pick a subject only for overlap. If you dislike the subject, the overlap advantage will not sustain in the long run.

5. Academic Background

If you have a graduation or post-graduation background in a subject, it often makes sense to choose that as your optional. Why?

You are already familiar with basic concepts and terminologies.
You may have notes or professors you can reach out to.
You can revise faster and delve deeper into advanced topics with less effort.

For instance, engineering graduates sometimes pick Mathematics or Electrical Engineering, while commerce students may choose Commerce and Accountancy.

However, this is not a rule. Many aspirants opt for entirely new subjects and still score exceptionally well. For example, several MBBS graduates have chosen Anthropology over Medical Science because it is concise and easier to master.

6. Length and Manageability of the Syllabus

A subject with a vast syllabus might require more time for first-time aspirants. If you’re appearing in the exam for the first time, balancing four GS papers, an essay, and an optional with a very wide syllabus may become overwhelming.

For example:

Geography and History are rich in content but vast in coverage.
Philosophy and Sociology are relatively shorter and more manageable.

A short and crisp syllabus can help in multiple revisions, which is the key to writing high-scoring answers in UPSC Mains.

7. Success Rate and Toppers’ Choices

Each year, UPSC releases statistics showing the success rates of optional subjects. While these numbers should not be the sole deciding factor, they do provide a rough picture.

Subjects like Anthropology, PSIR, Sociology, and Geography have consistently featured among top performers. Looking at the choices of recent toppers, and how they prepared for those subjects, can offer useful insights.

8. Nature of the Subject – Static vs Dynamic

Some optional subjects are mostly static (limited change over years), while others are dynamic (need constant update from current affairs).

Philosophy, Sociology, Anthropology – mostly static.
PSIR, Geography, Public Administration – blend of static and dynamic.
History – largely static but questions demand conceptual depth.

If you are someone who enjoys reading current affairs and applying them in theory, dynamic subjects like PSIR may suit you. But if you want a more predictable preparation routine, a static subject could work better.

9. Language and Medium of the Subject

UPSC allows candidates to write their optional in a language of their choice. However, some subjects have better resources and coaching support in English or Hindi.

Ensure:

Standard books and coaching are available in your chosen language.
Terminology is not overly technical or alien to you.
You can write articulate, analytical answers in that subject’s language medium.

Popular Optional Subjects: A Brief Overview

Though there are over 25 optional subjects to choose from, a few dominate the scene. Here’s a quick glimpse of some popular ones:

Anthropology: Short syllabus, scoring, preferred by science grads.
Sociology: Easy to understand, overlaps with GS and Essay.
PSIR: Excellent overlap with GS Paper 2 and Essay, analytical nature.
Geography: Logical, diagram-rich, popular among science/engineering grads.
Philosophy: Small syllabus, abstract thinking needed.
History: Storytelling style, vast but overlapping with GS1.
Public Administration: Once a favorite, but recent papers have been tough.

Mistakes to Avoid While Choosing an Optional

Following the crowd or trends blindly – Just because many are picking a subject doesn’t mean it’s right for you.
Ignoring your own aptitude – If you dislike the subject, even the best resources won’t help.
Over-relying on coaching – Coaching can assist, but the drive to study must come from within.
Picking based solely on overlap – Overlap helps, but not if you can’t handle the subject.

Final Thoughts

There is no “best” optional subject in UPSC. The best optional is the one that aligns with your interests, preparation style, background, and strengths. The right choice can boost your morale, enhance your answer-writing skills, and ultimately reflect in your final marks.

Remember, thousands of aspirants have cracked the exam with a wide variety of optional subjects – from Physics to Philosophy. What made the difference was not the subject, but the depth, consistency, and quality of their preparation.

So, take your time. Reflect. Explore sample papers. Try reading an NCERT or two in the subject. Only when you feel a strong resonance with it, go ahead and lock it in. Your optional is not just a subject – it’s your ally in the UPSC battle.
