    Why Choose Electrical Engineering as optional

    Electrical Engineering optional is one of the very very famous optional for the top 10 rankers, The reason being, those aspirants who are very good at their engineering level will opt this optional subject treditionally. Also, this is very scoring though the syllabus is a bit high when compared to other optional subjetcs.

    One of the very important reason for selecting this optional is, with the same preparation, you can easily crack Engineering Service Exam as both the exams are conducted by UPSC only.

    Popularity of Electrical Engineering as an optional subject

    The following are the suggested books / references that the students can consult while preparing for Electrical Engineering - Main Examination - Paper I and Paper II.

    • Electrical Engineering is best fit as an optional for students who are passionate about the subject.
    • Since this is logical subject, scoring is quite straightforward and rote-learning is not required.
    • Engineering Electrical Engineering Students can score very well in this subject as only standard models of sums are asked in the question papers.

    Suggestions for Preparation of Electrical Engineering Optional Subject

    The following are simple preparation tips to score well in the Electrical Engineering - Main Examination - Paper I and Paper II.

    • Prepare selective topics and be thorough in these topics.
    • For Electrical Engg. People, Circuit Theory,Control Systems,E.M Theory,Energy Conversion,Measurements,Power Electronics and Power Systems are very easy to prepare,So concentrate on these topics to score very weill.
    • Similarly,for Electronics Engg. People, Circuit Theory,Control Systems,E.M Theory,Analog Elctronics,Digital Electronics,Microprocessor,Analog communication and Digital Communication,Measurements are very easy to prepare,So concentrate on these topics to score very weill.
    • Solve problems from previous years questions papers as the same models of the sums normally repeat every year.
    • Solve each problem highlighting each step while arriving at the solution. Do not skip any step thinking it is trivial.
    • Concentrate on the solved examples from Reference books suggested for the UPSC exam.
    • Monitor your speed during practice and try to improve it. Lack of time is the main challenge in this paper, as the solution of each problem will take considerable amount of time, practicing mock tests is far important than preparation.
