The level of comfort relies upon numerous elements like the familiarity of the subject, accessibility of books and other examination materials, availability of staff, recent trends of marks, the scope of peer discussion, the level of difficulty according to the syllabus and previous question papers and so on.

3. How to Shortlist from the Initial List of Optional Subjects
- Based on the above-mentioned criteria, prepare a list of 4-5 subjects that you think you have interest in.
- Now, go through the syllabus of each alternative subject. Read all topics precisely. Underline/ highlight the points that you think you know something about or have some interest in the syllabus of each shortlisted optional subject.
- Now go through the previous year question papers (3-4 years) of the shortlisted subjects. Read all the questions. Then again, measure yourself the level of interest you have or the knowledge you hold to answer each question. It’s just to know yourself how compatible you are with a subject, don’t stress on the off chance that you don’t know the answer to any question.
Two More Steps to Shortlist
- Finally, the availability of materials and guidance through training matters a lot. For a few papers, it is hard to get standard books, for some subjects coaching may not be available. Non-technical subjects can be prepared by doing self-study provided you consistently work on writing.
- By now you will have a reasonable picture of choosing between 2-3 papers. For instance, if you are from the engineering background and especially good at your engineering subjects, in the meantime if you have broadly read the literature of your native language, might be since your childhood, you will be in quandary to select between these two subjects.
Other Factors that Matters While Shortlisting
In this scenario, the ‘success rate’ counts. Generally, literature subjects have performed well in all years. You may wind up choosing literature of your native language as your alternative paper. It’s a decent choice.
For a few people who have worked in a big organization, Public Administration is a great choice and in fact, it has been the most prevalent option with working aspirants or with the individuals who have quit their jobs.
Medical students may settle on Medical Science, Zoology or Anthropology as these papers are related to their field.
The choice of selecting the alternative is an individual decision of every competitor as indicated by his/ her qualities and shortcomings. In any case, only the aspirant knows his/ her strengths, weaknesses, taste, and availability of study materials.
