Tips for GS 2 Answer Writing in UPSC Mains

By | February 2, 2024

Note: This is a free chapter from my book, Fundamentals of Essay and Answer Writing. I have previously published another excerpt on Introductions to Essay. The book has similar detailed chapters on Essay and answer writing for GS-1,2,3,4, and the Anthropology optional. You can get the book here.

GS-2 is tricky in the sense that it’s easy to find the sources and prepare from them, yet for many aspirants, scoring above 100 feels like an uphill task. In this chapter, we will break down the syllabus, examine each segment in detail, and discuss what changes you can bring in your preparation and answer writing to improve your scores.

Syllabus under GS-2 can be classified into two segments: 

  • Polity, Governance & Social Justice
  • International Relations. 

A mistake many aspirants commit while preparing for this paper is to put too much focus on the current affairs part, at the cost of the equally important static portion. Questions from this topic pertain to Constitution, Government schemes, laws, governance and development sector etc, linking them all to some current affair issue. But, it’s not enough to just know about the issue, you need to also connect it to the theory part of the syllabus. 

In the following sections, I lay out some fundamental guidelines for answering GS-2 questions.



Example: The local self-government system in India has not proved to be effective instrument of governance. Critically examine the statement and give your views to improve the situation.

You can start the answer as follows: 

A: 73rd and 74th amendments to the Constitution established local self government in India. Some important articles pertaining to local government are 243A (Gram Sabha), 243B (Panchayats), 243G & 243W(Powers and responsibilities of Panchayats and Municipalities), 243 ZD & ZE (District and Metropolitan Planning Committee).

This is a simple rule of thumb for Polity related questions, but works remarkably well. Whenever you read a question that has some Constitutional relevance, simply start it with the article number. Mentioning the article number will convey to the examiner that you have an idea about the fundamental principles of the Constitution and how it operates. Also, memorising them serves another useful purpose. Sometimes, questions are based on the Constitutional articles themselves without revealing other details. If you can’t figure out what that Article is about, you will be in no position to attempt that question. For instance, consider the following question:

“The Supreme Court’s use of its vast powers under Article 142 may have done tremendous good. However, it’s time to have some checks and balances.” Critically analyse  the statement citing recent judgements.

If you don’t know what Article 142 refers to, you’ll be left clueless. Hence, it’s critical that you remember them like the back of your hand. At first, it might seem difficult to memorise so many, but with enough revisions, it isn’t that hard. Knowing Constitutional articles will help you across every stage and paper of the exam— Prelims, Essay, GS and even the interview. The complete list of important articles can be found on my blog


In GS 2, questions are usually asked on contentious topics where there is a possibility to take more than one view. In such questions, it helps to mention both sides of the argument even if not explicitly asked in the question and club them under relevant subheadings (arguments for/ arguments against) to mark a clear distinction between both. To illustrate, consider this question: “Simultaneous election to the Lok Sabha and the State Assemblies will limit the amount of time and money spent in electioneering but it will reduce the government’s accountability to the people. Discuss.” 

This is a debatable topic and one may agree or disagree with the statement. A common mistake aspirants commit is to take a side in the introduction itself and use rest of the answer to justify it repeatedly. A better approach is to present both sides of the topic with substantiation (data, facts, reasoning) and conclude the answer with what you think is right. 


Adding subheadings in the main body of the answer helps in two ways: One, it will help you break down the question into smaller, manageable chunks and two, it will help you stay close to the topic that’s being asked. It will convey to the examiner that you are precisely answering the question. For the question: Explain the salient features of the constitution (One Hundred and First Amendment) Act, 2016. Do you think it is efficacious enough ‘to remove cascading effect of taxes and provide for common national market for goods and services’?

Subheadings for this question would be:  

  • Salient Features of the Act
  • GST and Cascading Of Taxes 
  • GST and Common National Market
  • Problems in the current Act
  • Way forward/Suggestions

Observe how the terms in the subheadings closely mimic the terms in the question. They also make your answer easy to comprehend for the examiner. 


GS-2 is mostly analysis based paper with questions asking for your opinion. Merely writing arguments without facts and data would make your answers sound shallow. You must be armed with data and facts and mention them wherever apt. They make your arguments credible. If you want to say that India is struggling under the burden of NPAs— mention by how much, and what’s the trend of such NPA figures— is it increasing or decreasing? If you want to argue how India’s public health is in bad shape, back it up with numbers like IMR, high percentage out of pocket expenditure, MMR, scarcity of doctors, WHO standards etc., 

Further, you can also cite authentic reports from reputed international and national organisations to drive home your point. For instance, Transparency International report findings on corruption,  ASER on education etc.


These add incredible value and authority to your arguments. In Mains, it’s always the opinion of the experts that matter. We merely convey those expert opinions. Since Supreme Court is the ultimate interpreter of laws and the Constitution, we must know about the landmark judgments of the Apex court and use them wherever relevant. Below are some of the important judgments in independent India’s history. These are by no means exhaustive. If you think I have missed some important judgements, please add and memorize this list.

For this paper, every committee that’s in news is important. But apart from these current affairs related ones, there are a few core committees of the past whose observations and recommendations have remained timeless. You can quote them in your answers to substantiate your opinion, especially in the conclusion. The following list is not exhaustive. 

  • 1st ARC
  • 2nd ARC
  • Sarkaria Commission
  • Puncchhi Commission
  • Law Commission Reports


Illustrations and diagrams should be drawn when it meets two conditions: one, when it helps you express more content concisely and in less time. Two, it adds value and illuminates your answer by way of introducing or explaining a concept simply; conveying geographical spread on a map etc.

So if you find an info-graphic, a map or a graph in the newspaper or the internet, note them down and use them in your answers. In the Mains exam, I drew a diagram for the GST related question as below to show how it overcomes the problems of cascading taxes.

Mastering IR is about grasping a few fundamentals and applying them in your answers. Below is a list of such basics that you need to cover while preparing for this section.


With respect to every major bilateral relationship, you must know about the history and all the important agreements/treaties we had signed with those countries. For instance, Indo-Nepal treaty of Friendship, Kyoto protocol, Indo-Sri Lanka accord etc. might be dated agreements, but you must have a fair idea about them. List 4-5 core points of each agreement, and understand them. Adding these will add authority to your answers.  


For every current affair issue, have thorough factual knowledge related to it. Example: If International Court of Justice is in news, you must know about ICJ, its structure and mandate, how cases are referred to it etc., It will help you write better answers.


Understand the holistic relation that India shares with important countries such as US, UK, and other neighbouring countries. It can be categorised in the following way. 

  • Technological: Includes all the scientific and tech related relationship. For example, India-US collaborates to address tech initiative.
  • Economic: Trade and investment aspect of the bilateral relationship
  • Global fora: How India is cooperating with that particular country in various international groupings. For example, India – Japan relationship you can mention how we are working together in ASEAN, UNSC status, how Japan is helping us at Nuclear Suppliers Group etc.,
  • Strategic & Defence: In your answers, give specific names when you write about nuclear or defence cooperation. Mention the name of the equipment such as BARAK (Israel), Apache Helicopter (US), S-400 (Russia) etc. or various military exercises (SIMBEX, MILAN, Varun etc). 
  • Educational and Cultural: Any student exchange, tourism, establishment of universities, people to people contact initiatives etc.,

Also, prepare suggestions to improve the ties/overcome a challenge/way forward for each diplomatic relationship (this will inevitably form the conclusion for most of your answers)


Maps are the most versatile, useful tools for illustration in your answers. Whenever you see a question, think of ways by which you can present better through maps. Every IR question gives you scope to draw a map. You should practise enough so that so that you can draw and label them under a minute. 

For example: In India-China border dispute question, you can draw the following map and label the disputed areas.

India-China border dispute



In the context of the newly proposed amendment, discuss the need for establishment of a single, permanent tribunal to subsume existing tribunals with the purpose of speeding up settlement of Inter-State Water disputes.

Article 262 of the constitution deals with the resolution of inter-state water disputes. It envisages that:

  1. Parliament may provide for adjudication of inter-state water disputes
  2. Takes away powers of Supreme Court and other courts to entertain appeals against the tribunal award.

Issues with current system and need for a single tribunal

  1. Membership : Current system doesn’t specify term limits tribunal members.
  2. Award : 8 tribunals have been established so far, but out of them, only 3 gave final awards accepted by States.
  3. Delay in implementation : Many awards are appealed against in courts via PIL.
  4. Non-Publication of awards in gazette leading to festering of disputes
  5. Institutional problems such as no River Board established as per the River Board Act,1953 Eg : Kaveri award was given in 2007, but not implemented because of court litigation 

 How the new amendment speeds up settlement of water disputes

  1. The proposed new amendment Bill subsume existing tribunals to establish a single, permanent tribunal. 
  2. Time limits have been specified for awards (2 years, extendable by 1 year).
  3. Qualification of members, term limits are outlined clearly.
  4. Experts from hydrology, geology etc will provide technical inputs.
  5. Need for Gazelle publication is removed to expedite implementation.
  6. A dispute resolution committee (DRC) will help in setting disputes amicably without going to tribunal (time limit – 1 year)

Way Forward

Government must implement Mihir shah committee recommendations and establish a National water commission, subsuming Central ground water commission. Also, fora like Inter-state council, zonal council, NITI Aayog etc must be harnessed for better coordination and integrated water management.
