  • UPSC Optional Subjects – Choose the Best Optional Subjects for IAS

    The UPSC examination offers a wide range of optional subjects for the aspirants to choose from. In order to secure higher marks, it is important to carefully choose a suitable UPSC optional subject. The subject should be scoring and it helps if it has a small syllabus. The syllabus for the optional papers will be more than the bachelor’s degree and lower than the master’s level. Each optional subject for IAS comprises of two papers each of 250 marks, making it a total of 500 marks.

    IAS Mains Optional: Basis of Selection

    Your selection of the optional subject for IAS should be based on the following criteria:

    • Specifically defined and comparatively small syllabus.
    • Easy availability of study material.
    • Interesting and short subject material.
    • Scoring nature of the subject.
    • Availability of experienced guidance.

    The four papers of General Studies are divided as mentioned below –

    • Paper-I – General Studies-I – 250 Marks – (Indian Heritage and Culture, History, and Geography of the World and Society).
    • Paper-II – General Studies-II – 250 Marks – (Governance, Constitution, Polity, Social Justice and International relations).
    • Paper-III – General Studies-III – 250 Marks – (Technology, Economic Development, Bio-diversity, Environment, Security and Disaster Management).
    • Paper-IV – General Studies-IV – 250 Marks – (Ethics, Integrity, and Aptitude).

    How important is the Decision of UPSC Optional?

    The decision of UPSC Optional subject is very important. You need to select an optional subject in which you are comfortable to score high in UPSC mains. The level of comfort depends on many factors like the – familiarity of the subject, availability of books and other study materials, availability of faculty, the scope of peer discussion, recent trends of marks, the level of difficulty as per the syllabus and previous question papers etc.

    If the subject you took for graduation is available in the list of subjects given, in most cases the same option will turn out as a comfortable option. You can also look for an optional subject which you can finish in a time-bound manner without disturbing the time for GS preparation.

    A lot of candidates choose an optional subject because it is considered as a scoring subject. The score should not be the sole criteria for making a choice. Depending on the interest of the individual, the optional subjects for IAS should be shortlisted. Based on the shortlisted subject, the candidate should take a thorough look at the syllabus of the respective optional subjects for IAS.

    Factors Affecting Choice of Optional

    Interest towards the Subject

    In order to select the best optional, the first criteria should be the interest towards the subject. When an aspirant is interested in learning the subject, the process becomes much easier.

    Syllabus

    The syllabus and the requirement for coaching should be considered next. An optional with a limited syllabus is ideal since it will take lesser time for preparation and will have a chance of scoring higher marks. With a small and limited syllabus, it is possible to cover the subject within a period of 5-6 months. If the syllabus is limited, there will be a lesser requirement for coaching. Even if the candidate opts for coaching for the subject, the time period will remain between 3-4 months, which means there will be more time to prepare for the other papers. The decision to choose a particular UPSC optional subject should never be based on the popularity.

    Availability of Coaching and Reference Materials

    Coaching also plays a significant role in the selection of the optional subject for IAS. The aspirant will have to determine if coaching for the subject is easily available or not.

     In addition to coaching, the availability of reference books should also be considered. Every subject will require extensive reading and preparation, hence the optional subject for IAS should be chosen after considering all the aspects.

    Obsessiveness with Favourite Subject

    Do not blindly choose your favourite subject without having a look at the syllabus. It might be your favourite subject but it could have an extensive syllabus which will take up a lot of your time for preparation. Look for other options and analyze the syllabus before making an informed decision.

    An Overlapping Optional with GS

    Another trick is to choose two options which are related to one another. This will allow you to relate the concepts and also make the process of preparation easier. Any option you choose will help you in the GS paper. The GS paper forms the crux of the examination and the time you spent in preparing for the optional will also help you prepare for the specific subject of GS. GS covers various topics and requires a thorough knowledge of the same.

    IAS Mains Optional: What to avoid?

    • It is important to not choose a subject because a friend or a family member suggested it.
    • Do not opt for an optional just because it is what most of the aspirants have chosen. 
    • Candidates have managed to clear the exam in every optional and not a so-called high scoring optional.
    • Do not make your decision based on the option chosen for the past year toppers.

    Civil Services Mains Pattern in Detail

    The Mains Exam consists of 2 qualifying papers –

    • One is English and the other is a paper on any of the enlisted Indian languages. Both carry 300 marks each. However, their marks are NOT taken into account in the main examination.
    • According to the new pattern, there are 4 General Studies papers, each comprising of 250 marks with a total of 1000 Marks.

    Civil Services Mains Pattern & Marking Scheme

    The latest pattern along with the marking scheme is as follows –

    No.SubjectMarks
    1Indian Language (Qualifying) 300
    2English (Qualifying)300
    3Essay250
    4General Studies – I250
    5General Studies – II250
    6General Studies – III250

    8Optional Subject Paper 1250
    9Optional Subject Paper 1250
    TOTAL1750
    Interview (Personality Test)275
    Grand Total2025

    Thus, the Main examination has 9 papers.  All of them are subjective in nature.

    Thus, it can be rightly concluded that choosing an optional subject for IAS should be based on an individual’s interest and liking for a subject. There is no ideal optional subject to clear the examination; it always depends on the dedication in terms of preparation for the exam. The optional subject should be chosen keeping in mind your knowledge base and interest in the particular subject area.

        Hi Abhilasha,

        If you are interested and have good command over the maths, then go for it.

        Before finalising your optional, just refer the Mains syllabus and last few years Mains question paper of Mathematics.
