Is Medical Science a good optional for IAS?
Medical science is a good optional for doctors who are comfortable with studying their MBBS syllabus once again. It would be a familiar subject as they would have dealt with it for five years. At the same time, the syllabus is considered vast and problematic if the candidate wishes to have overlap with the general studies papers. In this section, we discuss a few pros and cons of the medical science optional.
Medical science pros
- As a student of medical science, you would not have to start anything afresh in the syllabus. This is a big advantage.
- The syllabus is pretty much static.
- The questions asked are mostly conceptual and direct.
- If you follow the right strategy and work sincerely, you can score decent marks in this optional subject.
- The difficulty level of the UPSC medical science optional is slightly lower than the professional MBBS exam.
- This optional subject can be taken even by BDS or BAMS graduates.
- Finally, medical science is a scientific and rational subject. It is not subjective and so, marks are not subject to the interpretation of the examiner.
Medical science cons
- The UPSC syllabus for medical science is vast.
- There is no significant overlap with the general studies papers.
- You should have a genuine interest in studying the course, otherwise, it would be difficult to focus and finish the syllabus.
Keeping these pros and cons in mind, you should go through the UPSC medical sciences syllabus and previous years’ UPSC question papers. After that, assess your own knowledge levels and expertise and come to a decision regarding your optional subject. Choose wisely as the optional, that contributes to 500 marks in the UPSC total, can make or break your IAS attempt.

General tips for medical science optional
- Diagrams are extremely important in this paper. Draw neat diagrams even if they are not explicitly asked in the question. Presentation is very important. You can score more marks with less number of words if you draw diagrams to represent what you are trying to convey in your answer. Some toppers also recommend drawing with colour pencils to make the presentation good and appealing if you get the time.
- Even in forensic medicine, you should use diagrams.
- Paper-II is more dynamic than Paper I. It contains case studies and it would be good if you can refer a few PG books for questions on the same. It is an added advantage if you can take the help of your seniors who are practising medicine for tips on such case studies.
- When there is a choice of questions between static questions and questions on forensic medicine, it is better to stick to direct questions. Forensic medicine deals with subjective topics like suicide, rape, etc., so it is advisable to stay clear of it when presented with a choice.
