Mechanical Engineering Optional UPSC: Strategy, Booklist, Notes, Answer

Mechanical Engineering optional UPSC Startegy Booklist and Topper AnswersMany UPSC Aspirants with Mechanical Engineering background ask how is mechanical engineering optional for UPSC. Here I will discuss strategy for mechanical engineering optional which is very high scoring if prepared properly. I have also given topper’s answers to previous year questions of mechanical engineering optional by me and Vivek Kumar, IAS


UPSC Mechanical Engineering Optional Strategy

I did classes for GATE from Made Easy. So, I made class notes as the base, and further kept adding topics from varied sources as per CSE syllabus. For numerical practice, me and my friend Vivek solved the previous year questions separately, and then compared and discussed our solutions.

Some suggestions for Mechanical Engineering Optional:

  • Make previous year questions as your guiding compass. Identify and prioritise the favourite topics of UPSC. (Solutions for previous year questions are now available in the market)
  • Don’t leave any topic of syllabus untouched. Cover at least the basics of all the topics
  • Prepare short notes of formulae and other facts, figures and diagrams for last minute revisions. It gives immense confidence just before the exam
  • Revise syllabus and questions as many times as you can
  • Practice solving papers in time bound manner
  • Question selection is important. For instance, in a question, if choice is given, sometimes one of those choices can be solved in 5 minutes, whereas the other choice may take 15 minutes to solve. So, try to develop a judgement for question types during practice itself. It’ll help you in exam in time management and not getting stuck in difficult questions
  • Avoid silly mistakes in numericals. Find right balance between speed and efficiency. For instance, I tried to maximise my attempt, but without making silly mistakes. So I attempted 425/500

    SSA sir and Thank You for the detailed strategy and notes.
    My Queries Are :

    1. Do we get step marking if in case our numerical answer goes wrong. (E.g. like 70% of allotted marks for wrong answer but correct steps) ?

    2. In numericals that are direct formulae based, do we need to derive it also(or directly use it)?
