Doctors and engineers sit the same Civil Services Exam as everyone else, under the same rules. But UPSC's notice has a few lines that matter particularly to you: optional subjects in medical science and in three branches of engineering, a different level for those optional papers, and a rule for MBBS graduates who have not yet finished their internship.
This guide covers those rules, then offers advice on choosing an optional and preparing the General Studies papers. The rules are UPSC's; the advice is ours.
Eligibility: the internship rule
- Passed MBBS, internship not finished. If you have passed the final professional MBBS or an equivalent medical exam but not finished your internship when you apply, you are admitted provisionally. With your application you submit a certificate from your university or institution that you passed the final professional exam.
- Proof by the interview. At the interview you must produce your original degree, or a certificate from the university or institution that you have completed every requirement for it, internship included. The notice asks for proof of internship for MBBS, BDS, veterinary science and similar degrees.
- Engineers. An engineering degree is a graduate degree like any other. The notice also accepts professional and technical qualifications that the Government recognises as equivalent to a professional or technical degree.
The age limits and attempts are the same for everyone; see eligibility criteria and the age calculator.
Optional subjects from your field
The notice's list of optional subjects includes Medical Science, and Civil, Electrical and Mechanical Engineering. It also has science subjects that may overlap with your degree: Physics, Chemistry, Mathematics, Statistics, Botany, Zoology, Geology, Agriculture, and Animal Husbandry and Veterinary Science. Each optional has two papers of 250 marks, and both count towards your rank.
- Engineering and medical science are set at bachelor's level. The notice sets most optional papers at honours-degree level, above a bachelor's and below a master's. For engineering, medical science and law, it says the level corresponds to the bachelor's degree.
- You are free to choose any optional. The notice lets every candidate choose any one subject from its list. A doctor can take sociology, and an engineer can take history.
- Calculators are allowed. Scientific, non-programmable calculators may be used in the essay-type papers, which matters for numerical optionals. Programmable ones are treated as unfair means.
- Past papers are on UPSC's site. UPSC's previous question papers include Medical Science and the engineering optionals for every year from 2016. See previous year papers.
The full syllabus of each subject is in the optional subjects list; for medicine, see the Medical Science optional syllabus.
Your subject or another one?
We make no claim that any optional is easier or more successful than another. Weigh these instead:
- Overlap with what you know. Compare the optional's syllabus with your degree, line by line. A large overlap saves time.
- How long since you studied it. If you graduated years ago, or work in a narrow field, your degree subject may need nearly as much fresh work as a new one.
- Whether you still enjoy it. You will study the optional for a long time. Interest helps you keep going.
- Overlap with General Studies. Some optionals share ground with the GS papers, which can save time across both.
- The style of the papers. Read and attempt a few questions from the last few years of each subject you are considering. Numerical and descriptive papers suit different people.
More on this in choosing an optional subject.
Preparing the General Studies papers
- Science helps in parts. The prelims syllabus includes general science, and GS III includes science and technology. Your background is an advantage there.
- Most of GS is not science. History, culture, geography, polity, governance, society, international relations, economy and ethics make up most of the syllabus. Plan more time for these, and start with the NCERT books.
- Write in prose, not notes. The mains asks for relevant, meaningful and succinct answers within word limits. Practise structured paragraphs rather than the shorthand of technical exams. See mains answer writing.
- Don't assume CSAT is easy. It tests comprehension and reasoning as well as numeracy, and you need 33% to qualify.
Other UPSC exams for your field
UPSC's 2027 calendar also lists the Engineering Services Examination and the Combined Medical Services Examination. These are separate exams with their own notices. This guide is only about the Civil Services Exam.
Frequently asked questions
Can I apply for UPSC before finishing my MBBS internship?
Yes. If you have passed the final professional MBBS exam, you are admitted provisionally, with a certificate of passing from your university or institution. At the interview you must produce the degree, or a certificate that you have completed every requirement for it, internship included.
Do engineers have to take an engineering optional?
No. The notice lets every candidate choose any one optional from its list, whatever their degree.
What level are the engineering and medical science optional papers?
The notice says they correspond to the bachelor's degree, as does law. Most other optionals are set at honours-degree level, between a bachelor's and a master's.
Can I use a calculator in the mains?
A scientific, non-programmable calculator is allowed in the essay-type papers. Programmable calculators are not, and calculators are not allowed at all in the objective prelims papers.
