How to Prepare Mechanical Engineering Optional for UPSC | Syllabus, Booklist & Strategy for UPSC Mechanical Engineering Optional

UPSC also offers engineering subjects as an optional subject for UPSC Civil Services (Main) examination. The subjects offered under engineering are mechanical, civil, and electrical engineering, all three of which are core branches of engineering. Now, it goes without saying that you have to be a graduate in subjects if you were to take this optional. Although anybody can opt for any subject, mere interest in any of such specialized disciplines would not make it the best fit for you.

Generally, there are very few takers for mechanical engineering optional subject for UPSC. Most of the candidates who take up engineering subjects are IES (Indian Engineering Services) aspirants too. In this article, we will discuss the UPSC Mechanical Engineering optional syllabus, booklist and a robust preparation strategy.

Pros And Cons of Mechanical Engineering Optional For UPSC

Pros of Mechanical Engineering Optional

  1. Objective Nature of Paper: The paper of mechanical engineering or any other technical subject is objective in nature which means that there is only one right answer for the question that is being asked, your personal opinion or views do not matter much. Therefore, the scores in this paper do not vary much if you are writing the correct answer.

  2. Familiarity with the subject: Engineers who have studied this subject for four years in their graduation would naturally be more familiar with the subject in comparison to other humanities subjects.

  3. Difficulty Level of the exam: The difficulty level of the questions are not that high, it is pretty much similar to the level of graduation or probably one notch higher than that.


Cons of Mechanical Engineering Optional

  1. Vast Syllabus: The syllabus is undoubtedly extremely vast which will require you to study it for a longer time than any other humanities optional. It will, therefore, lessen the time that you will get for your General Studies preparation.

  2. No Overlap:While other humanities subject may find a decent overlap in the syllabus, with technical optional subject, there is no scope for any overlap.


Booklist for Mechanical Engineering Optional For UPSC

Preparation Strategy for UPSC Mechanical Engineering Optional

  1. Step zero should be to get a hang of what kind of questions are being asked in the examination. Refer to the previous year’s papers and analyze them thoroughly. This will give you an idea of what exactly you need to prepare and the depth of knowledge you should have.

  2. Next, go for studying the theoretical aspects of the syllabus from the standard books and notes that are available. You can leverage NPTEL lectures and Made easy notes to cover this part.

  3. Then, go for solving numerical problems. Start with solving solved examples from standard textbooks. Once you have done that, go for solving the numerical from previous year papers.

  4. The next and the most important part of the preparation strategy is the thorough revision that you should incorporate into your preparation on a daily, weekly, and monthly basis. Try to revise the entire syllabus at least twice before the Mains examination.
