The UPSC exams are regarded as one of the nation’s toughest admission tests due to its difficult questions. Students therefore put forth a lot of effort to pass UPSC Prelims. You can improve your chances of passing the IAS exam, nevertheless, if you pay attention to the following advice.

Step 1 – Understand the Exam

  • If a student does not understand the exam’s content, they cannot perform well on it. Understanding the topics that can be included in the examination is just as crucial as knowing the type of exam that will be given.
  • All of this information is published by the UPSC in a document that can be seen on their website. Before beginning their preparations, students must also thoroughly comprehend the eligibility requirements.
  • All of this falls under the category of examination preparation. To avoid confusion on, or a few days before the tests, concerning these little things, this must be done as the first step. Starting with these crucial aspects enables you to progress through the preparation process in a more organized and systematic way.

Step 2 – Start Reading

  • The simplest way to learn is to use your old schoolbooks. The NCERT books can be used to study the whole syllabus for the UPSC exams.
  • You can download your old textbooks for free if you can’t find them. Although you may have retained the majority of the concepts while reading, it is nevertheless advisable to review them twice for better self-preparation.
  • You must be familiar with the syllabus and the paper structure after finishing step 1. Now that you know this, you can start your actual exam preparation.
  • You should also start reading the most recent news. In the General CSAT exams, current events are the source of the majority of the questions.

Step 3 –   Read and Write

  • After we finish our education, one of the habits we drop is learning by writing. While many individuals do it in school, after it is over people tend to concentrate more on quickly skimming a book’s contents in order to memorise it.
  • While this might be effective in a classroom setting, you must write in order to prepare for the UPSC exams.
  • Writing allows you to learn a subject twice: the first time when you read it aloud and the second time when you write it.
  • More significantly, though, it mentally ingrains the subject in your mind. So, after you have finished looking through the books in your first round, you must locate your old notebooks and start outlining your topic.

Step 4 – Take mock exams

  • You must take numerous practise exams after thoroughly preparing for the exam. There are many websites that provide you with sample questions from previous exams that you can take.
  • This step in your preparation is essential since it gives you a better idea of what an actual exam will be like.
  • You must follow the time constraints and take it honestly. This will not only help you better manage your time, but it will also make it easier for you to see your errors and ease your anxiety before the big paper.

How To Choose The Best UPSC Optional Subjects For UPSC Exam

The optional subject has a significant impact on how UPSC candidates score. Two of the nine exams in the CSE Main exam, Papers VI and VII, are from the UPSC optional topic. Subject Paper 1 and Subject Paper 2 are optional. They each carry 250 marks. In the UPSC Mains Exam, the UPSC optional subject hence carries 500/1750 points. The final merit is computed by taking into account the marks earned in the optional UPSC subjects. However, the ideal optional subject for UPSC selection must be made using a professional technique.

Therefore, it is important to choose an optional subject for the UPSC carefully. Since applicants must now select just one optional subject, “how to select the best optional subject for UPSC” continues to be the most often posed query among UPSC aspirants.

Significance of Optional Subject

Only the optional subjects are available to candidates for the Civil Services Exam (CSE) and are taken into account when determining merit. The following papers are all identical for everyone or just serve as qualifications.

  • The UPSC CSE’s optional topic test is the key to success. You might not be able to make much of an impact on the GS Mains exam, but if you pick the proper choice and put in the necessary work, you could even lead by 20 to 50 marks in the optional exam.
  • In the UPSC CSE, selecting the appropriate optional is a crucial decision.
  • The reason for this is that there is a greater chance of getting higher marks in the optional category than in the General Studies (GS) Mains test or any other category:
  • A GS Mains topper often receives between 475 and 525 out of 1000, or 50% of the exam’s total marks, despite the fact that the GS Mains exam has a weightage of 1000 points and typically takes two to three years to complete.
  • The best scorers in optional topics, on the other hand, typically get scores between 350 and 370 out of 500, or more than 70% of the possible points.
  • Therefore, even though the optional subject exam has a lower weight than the GS Mains exam, there is a considerably greater chance of doing well in the optional exam than there is in the GS Mains exam.

Choosing Optional Subject

·  Contrary to State PSC Exams, UPSC only advocates moderation and does not scale back optional subjects.

·  Scaling is the process of comparing the results of two (or more) optional subjects. It is accomplished by assuming that the students’ academic levels are comparable.

· Assuming, for example, that the student receiving the greatest scores in Anthropology is on par with the student receiving the highest marks in Mathematics, etc.

·  This assumption is rejected by UPSC, which instead adopts a moderate stance.

· For instance, if a student received additional marks from a subject examiner, the chief examiner will reduce (moderate) the scores based on the student’s knowledge.

Which UPSC Optional Subjects Has Most Overlap With General Studies Subjects?

Because of the substantial overlap with GS or other sections of the UPSC test, the following UPSC Optional subjects are popular among IAS students from both technical and non-technical backgrounds:

  • Public Administration – Highly relevant, compact syllabus, paper II (Indian Administration) has a lot of overlap with polity and governance part in GS II.
  • Sociology – the study of society, lots of material which can be used in GS I, Essay, and even in Ethics paper.
  • History – relevant for prelims as well as GS I.
  • Geography -relevant for prelims as well as GS I
  • Political Science – relevant for prelims as well as GS II
  • Law – relevant for prelims as well as GS II

Optional subjects in UPSC like Economics, Philosophy, and Agriculture are also good choices.

Strategy for Studying UPSC Optional Papers

·  Both objective and subjective type subjects have an equal possibility of giving you a good result; neither has a greater marking pattern than the other. It is a relative standard based on one’s own abilities rather than an absolute one.

·  Some topics, like philosophy, have a smaller length and width but a greater depth. On the other hand, history is a very broad subject with a significant length and width but a limited depth. If depth is taken into consideration, the time required to fully understand any optional subject would be nearly the same.

·  You should determine the plan at the end. One of the best strategies would be to first finish the entire GS syllabus and then select the best alternative for you.

·  You have two options for studying: pipelining or parallel study (many tests; GS, essay, Optional, at once).

·  A subject must be factual in order to be considered objective, and there can only be one specific, right solution. Subjects that can be objectively studied include math, physics, and to some extent, geography.

·  Subjectivity, on the other hand, denotes the possibility of more than one correct/appropriate response to a query (and a subject). Subjective fields include political science, sociology, anthropology, literature, and more.

Best optional subject in UPSC

  • The candidates’ top three choices for optional coursework were geography, political science and international relations, and sociology.
  • Hindi literature has recently gained popularity as an elective among students taking the main exam and passing the CSE.
  • Some topics receive higher grades than others. However, if we take a closer look, both technical and non-technical areas typically yield scores higher than 320 for IAS top performers. Because applicants lack the required effort or because they choose an optional subject for UPSC that isn’t a good fit for them, several subjects are said to be low-scoring.
  • Technical disciplines like mathematics can help you score well because the solutions are set in stone. Contrary to subjects in the humanities, the biases or preferences of the examiner essentially have little bearing.
  • However, non-technical disciplines give you more preparation time and reading material overall, helping you prepare effectively for the IAS Mains test, particularly those that overlap with the General Studies syllabus.

Below is a list of these popular subjects –

Some Important Tips:

  • When studying the material for the optional subject exam, you shouldn’t be picky. There is still work to be done on around 90% of the subject’s syllabus.
  • It is preferable to read a reputable journal from your related field. Examine specialised journals, quality articles from reliable sources, and publications like The Hindu and Indian Express.
  • In your responses, make an effort to include recent publications, indices, polls, or the recommendations of a reputable group. Using credible sources to support your points boosts the authenticity of your response.
  • Take note of recent studies, books, articles, reports, indices, and their distinctive findings and conclusions as you analyse current events. Since it’s quite likely that the questions on the optional exam will be repeated, preparation for the optional subjects should only be finished once you’ve practiced all of the questions from the previous year.

Conclusion

In the UPSC CS Main Examination, the UPSC optional subjects are crucial. Out of a total of 2025 marks, it comprises of 500 total marks. If you make the right decisions, these 500 points can significantly alter your ultimate score. Depending on the candidate’s educational background, each candidate may have a different notion of the best UPSC optional subject from the list of UPSC optional subjects. The majority of students make the error of selecting optional subjects for the UPSC based on the performance of the top candidates in that subject or due to other considerations like popularity, the availability of study groups, etc. To avoid losing an attempt, you should use extreme caution while selecting an optional subject on such grounds.
