This is very important decision. Fortunately in the new format General Studies (GS) is much more important. So don’t take this decision at the beginning. First start preparing for GS and then after some time take this decision. Because in four GS papers you will be introduced to variety of optional subjects like History, Geography, Public Administration, Political Science and Sociology. This will help you to determine your inclination to a particular subject. Every subject has its own demand (i.e. thinking pattern, writing style, presentation techniques etc). Your personality should suit to it.
The new shift in Civil Services Main examination has not resolved the dilemma of choosing the optional subject. The candidates keep on asking what subject they may take as optional to score high marks.
The popular choices among candidates are; Public Administration, Sociology, Geography, History, Political Science and Philosophy. More than 80% of the test-takers opt for these subjects. This is because all these subjects overlap with general studies. Among them Public Administration is the most popular choice. However, question remains do they fetch high marks?
There are some thumb rules for selecting the optional subject. First, you should not select the subject, if you are not comfortable with it. Normally one should select subject studied at the graduation level. The criteria of the choice of subject should be as per your interest, rather than having studied them at the graduation level.
Also keep in mind that you may have been proficient in a subject, but lack of touch may make it tougher to re grasp the same subject. This applies for technical subjects. In such case it is advisable to take a fresh subject. If you are engineering, medicine or science graduate and have been working for some time, you may have lost touch with your core subjects of graduation days. In such case it is advisable to take new subject which is easy to grasp.
The selection of a subject should be based on the availability of the study material. A huge study material is available for subjects such as History, Sociology, Anthropology, Geography, Political Science, Psychology and Public Administration.
Remember, the competition is among the people who have opted for the same subject. The social sciences papers have huge number of takers and due to it scoring high marks in these subjects are extremely difficult. So if you are comfortable in a subject that has minimum rush, there are chances of scoring good marks is more.
However, it all depends on how much time you can spend every day on your optional subject. Even with the subjects of your liking some time is needed to prepare them. If you're basic concepts of any science or technical subject is clear, then go for it, else opt for a social science subject. Many science, medicine and engineering students are opting for a social science subjects. They are easy to grasp provided you have a good memory.
The other rule of the selection of optional subjet is to analyze the syllabus thoroughly. After that look for the question papers of the previous years, and analyze its past trends. This has to be done at the very beginning and some time has to be spent on it to make a final call on it. Once you make up your mind selecting your optional subject, take a plunge into it and never regret of not choosing any other optional subject.
Last but not the least get some feedback/advice from those who have qualified examination on the subjects they had taken as optional to write their mains examination. You must ask them how much marks they scored in the two papers of the subject. Also take some tips on the study material and the way they went about its preparations. Sometimes, such views are printed in the competitive magazines, you have to go through them and develop your own ideas based on them in choosing an optional paper.
